HELP SECTION
PCPLT
Type: Task
Use: To create one or more plots (on the TV or plot files) of the
selected pulse-cal table. The plots will be a set of profiles
separated on the vertical axis by an increment in time or
antenna number (depending on the sort selected). More than one
plot for more than one antenna or more than one time may be
generated. Multiple IFs and polarizations will be plotted
along the horizontal axis if they are present in the PC table
and selected by the adverbs.
Pulse-cal amplitude, phase, or residual phase may be displayed.
Residual phase is that phase remaining after on-the-fly fitting
of a delay and phase to each IF in each time and antenna
sample. Computation of the residual is requested with adverb
DOCALIB and display of residuals is requested by the various
CODETYPEs.
Adverbs:
USERID.....Input file user number. Ignored
INNAME.....Input UV file name (name). Standard defaults.
INCLASS....Input UV file name (class). Standard defaults.
INSEQ......Input UV file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input UV file. 0 => any.
INEXT......table type ignored, 'PC' always used
INVERS.....Specifies the version of the PC table to be read as
input. 0 -> highest.
FREQID.....Specifies which freqiency ID to plot. 0 => 1.
SUBARRAY...The subarray number to be plotted. 0 => 1.
TIMERANG...Time to be plotted: start day, hour, min, sec, end day,
hour, min, sec. T1 = T2 => plot and average all times.
T1 < T2 => average over T1 through T2 and plot T1 through
T2; T1 > T2 => average all times but plot only T2 through
T1.
BCHAN......Lowest channel of a range of channels to be plotted.
0 => 1.
ECHAN......Highest channel number to be plotted. 0 => highest.
BIF........Lowest IF to be plotted. 0 => 1
EIF........Highest IF to be plotted. 0 => highest.
STOKES.....If the first character is R or L then only that
polarization is plotted. Otherwise both are plotted if
present. If two Stokes are present, 'I' will plot
(R+L)/2 and 'V' will plot (R-L)/2 for PC tables only.
ANTENNAS...A list of antennas to be included. all 0 => include all
If any in the list is negative, then include all antennas
except and that appear (in absolute value) in the list.
Thus ANTEN = 3,-5,7 inlcudes all antennas except 3, 5,
and 7.
CODETYPE...'AMP ' to plot the amplitude of the pulse-cal spectrum.
'PHAS' to plot the phase of the pulse-cal spectrum.
'REAL' to plot the real part of the pulse-cal spectrum.
'IMAG' to plot the imaginary part of the pulse-cal
spectrum.
'DIFA' to plot the amplitude of the vector difference
between the current pulse-cal spectrum and the
average pulse-cal spectrum for the selected time
or antenna
'DIFP' to plot the phase of the vector difference between
the current pulse-cal spectrum and the average
pulse-cal spectrum for the selected time or
antenna
'DIFR' to plot the real part of the vector difference
between the current pulse-cal spectrum and the
average pulse-cal spectrum for the selected time
or antenna
'DIFI' to plot the imaginary part of the vector
difference between the current pulse-cal spectrum
and the average pulse-cal spectrum for the
selected time or antenna
'ADIF' to plot the difference in the amplitude of the
current pulse-cal spectrum and the average
pulse-cal spectrum for the selected time or
antenna.
'PDIF' to plot the difference in the phase of the current
pulse-cal spectrum and the average pulse-cal
spectrum for the selected time or antenna.
The average pulse-cal spectrum is done with a scalar
average for amplitudes and a vector average for phases.
DOCALIB....> 0 -> attempt to fit the data for a delay and phasee in
each IF and polarization and subtract the
calibration from the observed phases before
plotting.
SORT.......Sort order for table. If SORT = 'TA', then each plot will
show all antennas at a particular time. Otherwise, each
plot will show all times for a particular antenna.
PIXRANGE...Clip plotted values with PIXRANGE. 0 => self-scale with
the max min for all solutions in the plot.
If PIXRANGE(2) < PIXRANGE(1), each small plot will be
self-scaled within its own plot area. Else all small
plots share the same scaling (which is frequently what
you will actually want).
Note that phase is initially computed in the range -180
to 180 degrees, but will be plotted in the range 0 to 360
if specified as such. In self-scaled phase plots, the
plot with the smaller total range of those two
possibilities is used. Values > 360 or < -180 are not
available.
FACTOR.....Controls the plot scale for each profile.
DO3COLOR...<= 0 => use a single line drawing color (TYPE 2).
=1 => the various pulse-cal spectra drawn are in a
range of colors from blue for the first spectrum
plotted (at the bottom) to red for the last spectrum
plotted (at the top).. Color distinguishes antenna
when SORT='TA' and distinguishes times otherwise.
=2 => use color as an additional separator of intensity.
The intensity range is assigned colors from blue at
the lowest value to red at the highest. Each point on
the plot gets the color appropriate to its intensity.
These color options allow the drawings to be more crowded
and still somewhat distinguishable.
LTYPE......Labelling type, see HELP LTYPE for details:
1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
relative to ref. pixel, 5 or 9 = relative to subimage
(BLC, TRC) center, 6 or 10 = pixels. 7-10 all labels
other than tick numbers and axis type are omitted.
Less than 0 is the same except that the plot file
version number and create time are omitted.
Add n * 100 to alter the metric scaling.
DOTV.......> 0 => plot directly on the TV device, otherwise make a
plot file for later display on one or more devices
(including the TV if desired).
GRCHAN.....Graphics channel (1 - 7) to use for line drawing. 0 => 1.
XYRATIO....Scale the X axis longer than the Y by XYRATIO.
If DOTV > 0, 0 -> fit to the TV window
If DOTV <= 0, 0 -> 1.
BADDISK....The disk numbers to avoid for scratch files (sorting
tables mostly).
