FLAG TIME
This option allows you to flag (delete) the solution for a specific
time.  Move the cursor to the time you wish to flag.  The vertical line
will follow it while the time and value of the solution nearest the
cursor will be displayed in the top left corner of the TV.  Once on the
desired time, hit button A or B to flag that time and loop for more, hit
button C to flag the time and return to the menu, and hit button D to
return to the menu with no further flagging.  As you flag a point, it is
changed in color in the editing and secondary area displays and may also
be changed in color in the plots of other antennas if those solutions
are also flagged..  Solutions for other polarizations, IFs, and antennas
may also be flagged depending on the setting of the ALL vs ONE POLARIZ,
ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the bottom left of
the display).  Note that, if the display is so crowded that more than
one time is plotted at the indicated cursor position (in the horizontal
direction only), then a range of times is actually flagged.  This option
is available in expert mode with abbreviation Time and code letter T (or
t).
C-----------------------------------------------------------------------
FLAG TIME RANGE
This option allows you to flag (delete) solutions from a range of times.
Move the cursor to the start or end time of the range you wish to flag.
The vertical line will follow while the time of the point under the
cursor will be displayed in the top left corner of the TV.  Hit button A
to switch to setting the other end of the time range.  Move the cursor
to the end point of the desired time range; the second line will follow.
Hit button A to switch between the begin and end times; hit button B to
flag the solutions in the specified range and loop to set another time
range; hit button C to flag the solution and return to the menu; or hit
button D to return to the menu with no further flagging.  Solutions for
other polarizations, IFs, and antennas may also be flagged depending on
the setting of the All vs ONE POLARIZ, ALL vs ONE IF, and ALL vs ONE
ANTENNA flags (shown at the bottom left of the display).  This option is
available in expert mode with abbreviation Rang and code letter R (or
r).
C-----------------------------------------------------------------------
FLAG BELOW
This option allows you to flag (delete) the solutions having value below
a cutoff level.  Move the cursor to the lowest level you believe in your
data.  The horizontal line will follow while the value of the point
under the cursor will be displayed in the top left corner of the TV.
Hit button A or B to flag all solutions below the chosen level and loop
to do it again, hit button C to flag all solutions below the chosen
level and return to the menu; or hit button D to return to the menu with
no further flagging.  Solutions for other polarizations, IFs, and
antennas may also be flagged depending on the setting of the ALL vs ONE
POLARIZ, ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the
bottom left of the display).  Note that the flagging is done on the
basis of the values of the selected solution type (ampl, phase, delay,
rate) of each polarization, IF, and baseline individually.  This option
is available in expert mode with abbreviation Belo and code letter B (or
b).
C-----------------------------------------------------------------------
FLAG ABOVE
This option allows you to flag (delete) the solutions having value above
a cutoff level.  Move the cursor to the highest level you believe in
your data.  The horizontal line will follow while the value of the point
under the cursor will be displayed in the top left corner of the TV.
Hit button A or B to flag all solutions above the chosen level and loop
to do it again, hit button C to flag all solutions above the chosen
level and return to the menu; or hit button D to return to the menu with
no further flagging.  Solutions for other polarizations, IFs, and
antennas may also be flagged depending on the setting of the ALL vs ONE
POLARIZ, ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the
bottom left of the display).  Note that the flagging is done on the
basis of the values of the selected solution type (ampl, phase, delay,
rate) of each polarization, IF, and baseline individually.  This option
is available in expert mode with abbreviation Abov and code letter A (or
a).
C-----------------------------------------------------------------------
FLAG AREA
This option allows you to flag (delete) the solutions from a range of
times and a range of solution values.  Move the cursor to one corner of
the area you wish to flag.  The box outline will follow while the time
of the data sample nearest the cursor within the box time range and the
value corresponding to the cursor vertical position will be displayed in
the top left corner of the TV.  Hit button A to switch to setting the
opposite corner of the area.  Hit button A to switch between the
opposite corners; hit button B to flag the solutions in the specified
area and loop to set another area; hit button C to flag the solutions
and return to the menu; or hit button D to return to the menu with no
further flagging.  Solutions for other polarizations, IFs, and antennas
may also be flagged depending on the setting of the ALL vs ONE POLARIZ,
ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the bottom left of
the  display).  Note that the flagging is based solely on the solution
values in the polarization, IF, and baseline displayed in the edit area.
When other polarizations, IFs, and baselines are also flagged it is
simply the same times as those selected within the box in the edit area.
This option is available in expert mode with abbreviation arEa and code
letter E (or e).
C-----------------------------------------------------------------------
FLAG POINT
This option allows you to flag (delete) solutions one at a time by
moving the cursor to the solution and hitting buttons A or B.  If you
hit button C, the current point is deleted and the program returns to
the menu.  Button D returns to the menu with no further deletion.
Solutions for other polarizations, IFs, and antennas may also be flagged
depending on the setting of the ALL vs ONE POLARIZ, ALL vs ONE IF, and
ALL vs ONE ANTENNA flags (shown at the bottom left of the display).
When other polarizations, IFs, and baselines are also flagged it is
simply the same time as that selected by the cursor in the edit area.
The cursor needs to be within 5 screen pixels of the solution and will
take the nearest sample if there is more than one within this radius.
This mode is useful for isolated outliers in a crowded display but is
more accurate in complex areas when used within a smaller frame.  This
option is available in expert mode with abbreviation pOin and code
letter O (or o).  This command flags only the selected point even if
multiple polarizations and/or IFs are displayed.
C-----------------------------------------------------------------------
FLAG QUICKLY
This option allows you to flag (delete) solutions one at a time by
moving the cursor to the sample (carefully keeping the left mouse button
untouched, i.e. up) and then clicking the left mouse button.  If you hit
buttons A, B, or C, the current point is deleted and the program returns
to the menu.  Button D returns to the menu with no further deletion.
Solutions for other polarizations, IFs, and antennas may also be flagged
depending on the setting of the ALL vs ONE POLARIZ, ALL vs ONE IF, and
ALL vs ONE ANTENNA flags (shown at the bottom left of the display).
When other polarizations, IFs, and baselines are also flagged it is
simply the same time as that selected by the cursor in the edit area.
The cursor needs to be within 5 screen pixels of the solution and will
take the nearest sample if there is more than one within this radius.
This mode is useful for isolated outliers in a crowded display but is
more accurate in complex areas when used within a smaller frame.  This
mode is very quick but requires you to be very careful in your use of
the mouse and left mouse button.  This option is available in expert
mode with abbreviation Quik and code letter Q (or q).  This command
flags only the selected point even if multiple polarizations and/or
IFs are displayed.
C-----------------------------------------------------------------------
RESTORE TIME
This option allows you to un-flag (restore) the solution for a specific
time.  Move the cursor to the time you wish to restore  The vertical
line will follow while the time of the point nearest the cursor will be
displayed in the top left corner of the TV.  Hit button A or B to
restore the solution at that time and loop for more; hit button C to
restore the time and return to the menu; or hit button D to return to
the menu with no further restoration.  Solutions for other
polarizations, IFs, and antennas may also be restored depending on the
setting of the ALL vs ONE POLARIZ, ALL vs ONE IF, and ALL vs ONE ANTENNA
flags (shown at the bottom left of the display).  Note that, if the
display is so crowded that more than one time is plotted at the
indicated cursor position (in the horizontal direction only), then a
range of times is actually restored.  WARNING: solutions that were
flagged in the input SN/CL table will be restored as well as any flagged
during the current editing.
C-----------------------------------------------------------------------
RESTORE AREA
This option allows you to un-flag (restore) the solutions from a range
of times and a range of solution values.  Move the cursor to one corner
of the area you wish to restore.  The box outline will follow while the
time of the data sample nearest the cursor within the box time range and
the value corresponding to the cursor vertical position will be
displayed in the top left corner of the TV.  Hit button A to switch to
setting the opposite corner of the area.  Hit button A to switch between
the opposite corners; hit button B to restore the solutions in the
specified area and loop to set another area; hit button C to restore the
solutions and return to the menu; or hit button D to return to the menu
with no further restoration.  Solutions for other polarizations, IFs,
and antennas may also be restored depending on the setting of the ALL vs
ONE POLARIZ, ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the
bottom left of the  display).  Note that the restoration is based solely
on the solution values in the polarization, IF, and baseline displayed
in the edit area.  When other polarizations, IFs, and baselines are also
restored it is simply the same times as those selected within the box in
the edit area. WARNING: solutions that were flagged in the input SN/CL
table will be restored as well as any flagged during the current
editing.
C-----------------------------------------------------------------------
SMOOTH TIME RNG
This option allows you to smooth (time average) the solutions from a
range of times.  Move the cursor to one end of the time range you wish
to smooth  The vertical line will follow while the time of the point
under the cursor will be displayed in the top left corner of the TV.
Hit button A to switch to setting the other end of the time range.  Move
the cursor to the end point of the desired time range; the second line
will follow.  Hit button A to switch between the begin and end times;
hit button B to smooth the solutions in the specified range and loop to
set another time range; hit button C to smooth the solutions and return
to the menu; or hit button D to return to the menu with no further
smoothing.  Solutions for other polarizations, IFs, and antennas may
also be smoothed depending on the setting of the All POLARIZ, ALL IF,
and ALL ANTENNA flags (shown at the bottom left of the display).
WARNING: solutions that were flagged in the input SN/CL table will be
smoothed as well as any flagged during the current editing.  Only the
selected solution type is smoothed, which may force you to repeat the
operation on other solution types.  Furthermore, this operation may only
be undone by the REREAD TIME RNG option.  See ENTER SMOOTH PS for a
description of the smoothing functions available.  The basic 2-point
smoothing is used solely to replace flagged solutions.
C-----------------------------------------------------------------------
REREAD TIME RNG
This option allows you to re-read from the output file the solutions
from a range of times.  Move the cursor to one end of the time range you
wish to re-read  The vertical line will follow while the time of the
point under the cursor will be displayed in the top left corner of the
TV.  Hit button A to switch to setting the other end of the time range.
Move the cursor to the end point of the desired time range; the second
line will follow.  Hit button A to switch between the begin and end
times; hit button B to re-read the solutions in the specified range and
loop to set another time range; hit button C to re-read the solutions
and return to the menu; or hit button D to return to the menu with no
further re-reading.  Solutions for other polarizations, IFs, and
antennas may also be re-read depending on the setting of the ALL vs ONE
POLARIZ, ALL vs ONE IF, and ALL vs ONE ANTENNA flags (shown at the
bottom left of the display).  WARNING: all solution types are re-read,
not just the selected type.  The solutions are read from the output
table.  Therefore, if only one IF is in memory at a time, these re-read
solutions may not be the same as in the input table.  The display is
updated as the solutions are read.
C-----------------------------------------------------------------------
ENTER SMOOTH PS
This option allows you to type on the terminal (main AIPS window) the
type and parameter(s) of the smoothing function.  The current type and
parameter(s) are displayed at the lower left of the screen.  The process
of smoothing is based on two windows on the time axis.  The cursor is
used to set a time-range (t1-t2) to be smoothed.  Data from t1-W to
t2+W, where W is the smoothing function window, are passed into a
smoothing routine and the results used to replace the samples in the t1
through t2 range.  The functions are:

(1) 2PT   Replace solution at time t, if flagged, with the linearly
          interpolated value of the nearest sample above t and below t
          but within W/2 of t.
(2) 2PTH  Replace solution at time t with the average of the solution
          itself and the linearly interpolated value of the nearest
          sample above t and below t, but within W/2 of t.
(3) BOX   Replace solution at time t with the average of all solutions
          within W/2 of t.
(4) MWF   Replace solution at time t with the median of all solutions
          within W/2 of t.
(5) GAUS  Replace solution at time t with the weighted average of all
          solutions samples within W/2 of t, using a Gaussian function
          of abs(time-t) of FWHM of W2.
(6) EXP   Replace solution at time t with the weighted average of all
          solutions samples within W/2 of t, using a Exponential
          function of abs(time-t) of FWHM of W2.
(7) LINE  Replace solution at time t with the weighted average of all
          solutions samples within W/2 of t, using a linear function of
          abs(time-t) of FWHM of W2.

The ENTER SMOOTH PS asks you 2 or 3 questions: the first to set the type
which is case-insensitive but must be left justified, the second to set
W in integer seconds, and the third, if needed, to set the full-width at
half maximum for the Gaussian and linear weighting functions.  The
smoothing is done without regard for source.
C-----------------------------------------------------------------------
ENTER WT RNG
This option allows you to type on the terminal (main AIPS window) the
range of solution weights that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of weight will cover this range, leaving out
any points outside the range (so be careful).  If you enter one or no
numbers or if the second number is <= the first, each weight plot will
be self-scaling.  The new weight range, if selected, is displayed
immediately on the TV unless the HOLD TV LOAD option was selected.  In
that case, the status code LOAD PENDING is shown and the DO TV LOAD
option is displayed and must be selected to see the new solutions.
C-----------------------------------------------------------------------
ENTER AMPL RNG
This option allows you to type on the terminal (main AIPS window) the
range of gain amplitudes that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of amplitude will cover this range, leaving out
any points outside the range (so be careful).  If you type 0 x, where
x <  0, then the  minimum of each plot will be 0 and the maximum will
be self-scaling.  If you enter one or no numbers or if the second
number is <= the first (but not the 0 x, x < 0), each amplitude plot
will be self-scaling.  The new amplitude range, if selected, is
displayed immediately on the TV unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new
solutions.
C-----------------------------------------------------------------------
ENTER PHASE RNG
This option allows you to type on the terminal (main AIPS window) the
range of gain phases that will be plotted.  It asks you for two numbers,
the lower limit and the upper.  If the upper limit is > the lower limit,
every plot of phase will cover this range, leaving out any points
outside the range (so be careful).  Otherwise, each phase plot will be
self-scaling.  The new phase range, if selected, is displayed
immediately on the TV unless the HOLD TV LOAD option was selected.  In
that case, the status code LOAD PENDING is shown and the DO TV LOAD
option is displayed and must be selected to see the new solutions.
If you enter one or no numbers, phase plots will be self-scaling.
C-----------------------------------------------------------------------
ENTER DELAY RNG
This option allows you to type on the terminal (main AIPS window) the
range of delay solutions that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of delays will cover this range, leaving out any
points outside the range (so be careful).  Otherwise, each delay
solution plot will be self-scaling.  The new delay range, if selected,
is displayed immediately on the TV unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new
solutions.  If you enter one or no numbers, delay plots will be
self-scaling.
C-----------------------------------------------------------------------
ENTER RATE RNG
This option allows you to type on the terminal (main AIPS window) the
range of rate solutions that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of rates will cover this range, leaving out any
points outside the range (so be careful).  Otherwise, each rate solution
plot will be self-scaling.  The new rate range, if selected, is
displayed immediately on the TV unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new
solutions.  If you enter one or no numbers, rate plots will be
self-scaling.
C-----------------------------------------------------------------------
ENTER MBDL RNG
This option allows you to type on the terminal (main AIPS window) the
range of multi-band delays that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of multi-band delay will cover this range,
leaving out any points outside the range (so be careful).  Otherwise
(e.g. 0 0), each multi-band plot will be self-scaling.  The new
multi-band range, if selected, is displayed immediately on the TV
unless the HOLD TV LOAD option was selected.  In that case, the status
code LOAD PENDING is shown and the DO TV LOAD option is displayed and
must be selected to see the new solutions.  If you enter one or no
numbers, muti-band delay  plots will be self-scaling.
C-----------------------------------------------------------------------
ENTER DISP RNG
This option allows you to type on the terminal (main AIPS window) the
range of dispersive delays that will be plotted.  It asks you for two
numbers, the lower limit and the upper.  If the upper limit is > the
lower limit, every plot of dispersive delay will cover this range,
leaving out any points outside the range (so be careful).  Otherwise
(e.g. 0 0), each dispersion plot will be self-scaling.  The new
dispersion range, if selected, is displayed immediately on the TV
unless the HOLD TV LOAD option was selected.  In that case, the status
code LOAD PENDING is shown and the DO TV LOAD option is displayed and
must be selected to see the new solutions.  If you enter one or no
numbers, dispersion plots will be self-scaling.
C-----------------------------------------------------------------------
USE EXPERT MODE
This option allows you to disable the menu as a form of command input
and change to entering one-letter commands from the main AIPS window.
The commands must be left-justified and followed by a carriage return
and may be in either case.  Prompt line(s) appear in the window showing
4-letter abbreviations of the available commands with the one-character
code shown in upper case.  Enter H or h for a display of the codes and
their translation into menu items.  Enter X or x to exit the expert mode
and return to input via the menu.  Note that only some menu items are
available in this expert mode and the full help information (such as you
are now reading) is not available.
C-----------------------------------------------------------------------
DO TV LOAD
This option will cause the TV display to be updated completely.  It is
only displayed if you have previously selected the HOLD TV LOAD option.
The reason to do this is to delay the screen update while you change
more than one of its parameters, i.e., the solutions type, display range,
antenna to edit, and/or secondary antennas.  The status code LOAD
PENDING is shown as soon as you have made a change which has not been
displayed.  When you select the DO TVLOAD option, it is replaced with
the HOLD TV LOAD option.
C-----------------------------------------------------------------------
HOLD TV LOAD
This option will cause the TV display to remain unchanged until the DO
TV LOAD option is selected.  The DO TV LOAD option is displayed if you
have previously selected the HOLD TV LOAD option.  The reason to do this
is to delay the screen update while you change more than one of its
parameters, i.e., the solutions type, display range, antenna to edit,
and/or secondary antennas.  When you select this option, it is replaced
with the DO TV LOAD option.
C-----------------------------------------------------------------------
REPLOT
This option will redo the full TV plot.  It may be of use if the plot
has not updated as expected.
C-----------------------------------------------------------------------
EXIT
This option is used to exit the program.  If you have done any flagging
or smoothing, the solutions will be written back to the output SN/CL
table.  The output table will remain cataloged as the previous highest
version number plus one.
C-----------------------------------------------------------------------
ABORT
This option is used to exit the program.  The output SN/CL table will be
destroyed.  Use this option if you have made no changes to the table, or
if you distrust the changes you may have made.
C-----------------------------------------------------------------------
NEXT POL/IF
If there are enough polarizations and IFs in the SN/CL table, this
option lets you switch to the "next" correlator.  It selects the other
polarization (if there are 2) and also selects the next IF if the
initial polarization was the highest available.  Thus if there are R
and L polarizations, it goes from R/1 to L/1 to R/2 to L/2 to ...,
eventually circling back to R/1.  If CROWDED was true, this option
changes the display to a single correlator even if > 1 IF or
polarization was plotted when it was selected.  The new data are
displayed immediately on the TV unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new data.
C-----------------------------------------------------------------------
SWITCH POLARIZ
If there are two polarizations in the solution table, this option lets
you switch between them to select the solutions to be displayed and
used in editing.  If CROWDED was true, then the display of both
polarizations at once is also selected by this SWITCH.  The solutions
for the new polarization are displayed immediately on the TV unless
the HOLD TV LOAD option was selected.  In that case, the status code
LOAD PENDING is shown and the DO TV LOAD option is displayed and must
be selected to see the new solutions.
C-----------------------------------------------------------------------
SWITCH ALL POL
This option lets you toggle between having the following flag, smooth,
and re-read commands apply to both polarizations and having them apply
only to the current polarization.  The status lines on the bottom left
of the TV screen reflect the current value of this option.
C-----------------------------------------------------------------------
ENTER IF
If you included more than one IF with adverbs BIF and EIF, this option
lets you select which one will be displayed and used in editing.  If
there are more than two IFs or CROWDED was true, you will be prompted
to type the number of the desired IF.    If CROWDED was true, you may
enter 0 to have all IFs displayed at the same time.  If there are just
two IFs (and CROWDED was false), the program simply switches to the
other one.  If flags are to be applied to a single IF, they are
applied to the IF selected with this option.  If all IFs were not read
into memory at the start of the job (due to lack of space), then the
solutions for the current IF are written to the output file (if any
flagging or smoothing might have been done) as the solutions for the new
IF are read in.  The solutions are immediately displayed on the TV
unless the HOLD TV LOAD option was selected.  In that case, the status
code LOAD PENDING is shown and the DO TV LOAD option is displayed and
must be selected to see the new solutions.
C-----------------------------------------------------------------------
SWITCH ALL IF
This option lets you toggle between having the following flag, smooth,
and re-read commands apply to all IFs, having them apply only to the
current IF, and having them apply to a range of IFs.  The last will
prompt you for the two IF numbers of a range of IFs.  If you only enter
one, then only that one IF will be flagged.  The status lines on the
bottom left of the TV screenreflect the current value of this option.
C-----------------------------------------------------------------------
SWITCH ALL TIME
This option lets you toggle between having the following FLAG ABOVE and
FLAG BELOW commands apply to all times and having them apply only to the
times displayed in the current edit window (the time range of the
frame).
C-----------------------------------------------------------------------
SWITCH ALL SOURC
This option lets you toggle between having the following flag commands
apply to all sources and having them apply only to the selected sources.
C-----------------------------------------------------------------------
SWITCH ALL ANT
This option lets you toggle between having the following flag, smooth,
and re-read commands apply to all antennas and having them apply only to
the current antenna.  The status lines on the bottom left of the TV
screen reflect the current value of this option.
C-----------------------------------------------------------------------
ENTER ANTENNA
This option allows you to type on the terminal (main AIPS window) the
number of the antenna to be used for the main display and for editing.
The solutions for the new antenna are immediately displayed on the TV
unless the HOLD TV LOAD option was selected.  In that case, the status
code LOAD PENDING is shown and the DO TV LOAD option is displayed and
must be selected to see the new solutions.  The solutions for this
primary antenna are displayed over the current time frame in the editing
and secondary display areas.
C-----------------------------------------------------------------------
ENTER OTHER ANT
This option allows you to type on the terminal (main AIPS window) the
numbers of up  to ten other antennas to be displayed above the display
of the main editing and secondary windows.  These comparison displays
use the same time frame and parameter type as the editing window.  To
display fewer than ten other antennas, simply hit Enter after listing
those that you do want.  You may have no comparison windows if you want
to see the largest possible display of the main editing window (hit
Enter with no non-zero values for this option). The data for the new
secondary antennas are immediately displayed on the TV unless the
HOLD TV LOAD option was selected.  In that case, the status code LOADg-
PENDING is shown and the DO TV LOAD option is displayed and must be
selected to see the new data
C-----------------------------------------------------------------------
NEXT ANTENNA
This option lets you change to the next antenna in EDITA's internal list
for your primary antenna.  The list of other antennas is not changed
unless the new antenna occurs there.  In that case, the new antenna is
removed from the list and a new higher numbered antenna is added at the
end of the list.  The edit and secondary viewing areas will now contain
data from the new primary antenna.  The data for the new antennas are
immediately displayed on the TV unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new data.
This option is available in expert mode with abbreviation Nant and code
letter N (or n).
C-----------------------------------------------------------------------
PLOT ALL TIMES
This option allows you to select the full time range of the solutions as
the range to be displayed in all windows.  The solutions for the new
time range are immediately displayed on the TV unless the HOLD TV LOAD
option was selected.  In that case, the status code LOAD PENDING is
shown and the DO TV LOAD option is displayed and must be selected to

C-----------------------------------------------------------------------
SELECT FRAME
This option allows you to select the time range in the solutions to be
displayed in the editing window using the TV cursor.  The solutions are
first re-displayed using the full time range in the solutions (unless
the full time range was already displayed).  Move the cursor to one end
of the desired time range.  Hit button A or B to switch to setting the
other time limit.  Note that you are allowed to make the time range as
large or small as you want.  Displays that have more than one time
plotted in a single horizontal TV pixel are harder to edit accurately
but will be quicker than having to do multiple frames when accuracy is
less essential.  Hit buttons A or B to switch to the other limit, hit
buttons C or D to select the frame and return to the menu.  The screen
is updated immediately, unless the HOLD TV LOAD option was selected.  In
that case, the status code LOAD PENDING is shown and the DO TV LOAD
option is displayed and must be selected to see the new solutions.  This
option is available in expert mode with abbreviation Fram and code
letter F (or f).
C-----------------------------------------------------------------------
NEXT FRAME
This option causes the current frame to change to the next higher time
range.  The "frame" is that time range in the solutions available for
editing in the edit window.  The width of the frame is not changed.  The
boundaries of the new current frame are shown in the top plot.  The
screen is updated immediately, unless the HOLD TV LOAD option was
selected.  In that case, the DO TV LOAD option is displayed and must be
selected to see the new solutions.
C-----------------------------------------------------------------------
PREVIOUS FRAME
This option causes the current frame to change to the next lower time
range.  The "frame" is that time range in the solutions available for
editing in the edit window.  The width of the frame is not changed.  The
boundaries of the new current frame are shown in the top plot.  The
screen is updated immediately, unless the HOLD TV LOAD option was
selected.  In that case, the status code LOAD PENDING is shown and the
DO TV LOAD option is displayed and must be selected to see the new solutions.
C-----------------------------------------------------------------------
TV ZOOM
This option allows you to set the zoom factor and center to blow up the
data plot for more accurate cursor positioning.  The display is actually
shown in zoom only during flagging, un-flagging and re-reading
operations (where zoom may help you point more accurately) and during
the setting of the zoom.  The cursor position controls the zoom center,
buttons A and B increment the zoom, button C decrements the zoom, and
button D ends the zoom setting and returns to the menu.  Instructions
appear on the terminal.  Note that selecting a small frame is more
accurate than simply blowing up a crowded display.
C-----------------------------------------------------------------------
OFF ZOOM
This option resets any zoom factors and zoom center.  The display is
actually shown in zoom only during flagging, un-flagging and re-reading
operations (where zoom may help you point more accurately) and during
the setting of the zoom.

SHOW WEIGHT
This option specifies that solution weights are to be displayed on the
TV and used in the editing.  The screen is updated immediately, unless
the HOLD TV LOAD option was selected.  In that case, the status code
LOAD PENDING is shown and the DO TV LOAD option is displayed and must
be selected to see the new solutions.
