HELP SECTION
TEPLT
Type: Task
Use: Plots selected calibration data versus time from a specified SN,
TY, PC or CL table.
To examine SN or CL tables with a new reference antenna, run
SNREF with DOKEEP=1 and then use TEPLT.
NOTE: FILLM and FITLD used to fill VLA and VLBA (resp) data
with CL tables having weight 0. These "data" (actually just
(1,0) for (real,imag) gain) are "flagged" and that may be the
reason for a failure to find any data to plot. Of course, you
are wasting time looking at (1,0)'s. CL tables with
interesting values in them will not be flagged in this way.
Adverbs:
INNAME.....UV file name (name). Standard defaults.
INCLASS....UV file name (class). Standard defaults.
INSEQ......UV file name (seq. #). 0 => highest.
INDISK.....Disk unit #. 0 => any.
INEXT......'SN','TY, 'PC', 'SY', or 'CL' table to be plotted
INVERS.....Version number of table to plot, 0=>highest no.
SOURCES....Source list. '*' = all; a "-" before a source name means
all except ANY source named.
QUAL.......Only sources with a source qualifier number in the SU table
matching QUAL will be used if QUAL is not -1.
TIMERANG...Time range of the data to be plotted. In order: Start day,
hour, min. sec, end day, hour, min. sec. Days relative to
reference date. If a start and stop time are given and
the XAXIS is 1 (time), then all plots will be from the
given start time to the given stop time. Otherwise, the
X-axis is plotted over the range of X values found in the
data. All plots in a given execution will be on the same
X scale in any case.
ANTENNAS...A list of the antennas to be plotted. All 0 => all. If any
number is negative then all antennas listed are NOT to be
plotted and all others are. NOTE: arrays such as the VLA
and MeerKAT have essentially the same values for all
antennas. It is better to select only one.
PIXRANGE...If PIXR(1) < PIXR(2), all plots will be from PIXR(1) to
PIXR(2). Otherwise each plot will be self-scaling.
NPLOTS.....Number of antennas to plot per page (try >1 for MULT,
1 otherwise.).
XINC.......Plot every XINC'th point, 0 => 1.
OPTYPE.....Data to be plotted on Y axis:
1. 'TIME' = time in days
2. 'HA ' = source hour angle degrees
3. 'AZ ' = source azimuth degrees
4. 'EL ' = source elevation degrees
5. 'AZIO' = ionosphere pierce point azimuth degrees
6. 'ZAIO' = ionosphere pierce point zenith angle degrees
7. 'DLON' = ionosphere pierce point longitude offset degrees
8. 'DLAT' = ionosphere pierce point latitude offset degrees
9. 'BX ' = Earth magnetic field away from center Gauss
10. 'BY ' = Earth magnetic field East Gauss
11. 'BZ ' = Earth magnetic field North Gauss
12. 'TEPA' = electrons per meter squared toward source
/ 10^16
13. 'MAG ' = Magntic field in source direction Gauss
14. 'TEC ' = vertical electrons per meter squared / 10^16
15. 'IFR ' = Ionospheric Faraday rotation rad/m/m
' ' => 'IFR'
. 'MULT' => plot multiple types as listed in APARM
using the type numbers given above.
OPCODE.....Type of X axis plot - same codes as above except MULT
' ' => 'TIME'
APARM......OPTYPE = 'MULT' only: Up to 10 types to be plotted. They
are identified by the numbers given in the OPTYPE
section.
BPARM......Corresponding minima of each plotted type.
CPARM......Corresponding maxima of each plotted type. 0's =>
self-scale.
DO3COLOR...<= 0 => use line type 4 for all points plotted.
> 0 => tells TEPLT to separate the plotted points
with color representing source. The list of source
numbers actually occurring in the table, time range,
source list, et al. is translated into consecutive
integers (in the same order) and then assigned red
through dark blue. Thus source numbers 1,2,5,10
become red, yellow, cyan, and blue, resp. no matter
what order they appear in the table.
SYMBOL.....Choices are
1: Plus sign 13: Star of David
2: Cross (X) 14: Seven-pointed star
3: Circle 15: Eight-pointed star
4: Box 16: Nine-pointed star
5: Triangle 17: Ten-pointed star
6: Diamond 18: 11-pointed star
7: Pentagon 19: 12-pointed star
8: Hexagon 20: 13-pointed star
9: Septagon 21: 14-pointed star
10: Octagon 22: Plus (+) with gap
11: Nine-gon 23: Cross (X) with gap
12: Five pointed star 24: Vertical line
FACTOR.....Scale plot symbols by FACTOR 0 -> 1.
If FACTOR < 0, draw lines between the points and use
abs(FACTOR) to scale the points plotted.
DOSCAN.....> 0 => plot scan boundaries when there is an NX table and
the X axis is time. The boundary is a tick mark when
DOSCAN=2 and a full line when DOSCAN=1.
<= 0 -> do not plot boundaries.
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.
A value of 0 causes more than one graphics channel to be
used.
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.
