FGPLT: Task to plot selected contents of FG file.
INPUTS
INNAME UV data (name).
INCLASS UV data (class).
INSEQ 0.0 9999.0 UV data (seq. #). 0 => high
INDISK 0.0 9.0 Disk unit #. 0 => any
INVERS FG table file version no.
0 => 1
TIMERANG Time range to plot
STOKES Stokes type to plot: R, L,
RR, LL, RL, LR
'' => 'R'
FREQID Freqid, 0=>1; -1=>all

BIF 0.0 100.0 First IF to plot, 0=>1.
EIF 0.0 100.0 Last IF to plot 0 -> highest
BCHAN 0.0 Lowest channel to include
ECHAN 0.0 highest channel to include
ANTENNAS Antennas to plot
BASELINE Baseline with antennas
LTYPE -410.0 410.0 Type of labeling: 1 border,
2 no ticks, 3 - 6 standard,
7 - 10 only tick labels
XYRATIO 0.0 X/Y ratio 0 -> fit TV or 1 PL
DOTV -1.0 1.0 > 0 Do plot on the TV, else
make a plot file
GRCHAN 0.0 8.0 Graphics channel 0 => 1.
HELP SECTION
FGPLT
Type: Task
Use: Plots selected data versus time from a specified FG table. If
all selected flags are antenna based, then an antenna-based
plot is done. If some are baseline based, then the plot is
done on a baseline basis.
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.
INVERS.....Version number of FG table to plot, 0 => 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. 0 -> take the time range from the UV
file. If the UV file is very short (usually a TASAV
file) then the time range is taken from the flag table.
It may be best to set TIMERANG in such cases.
STOKES.....The desired Stokes type of the displayed data.
R, L, RR, LL, RL, LR; '' => 'R'
FREQID.....Frequency identifier to select (you may determine which is
applicable from the OPTYPE='SCAN' listing produced by
LISTR).
-1 => all; 0 => 1
SUBARRAY...Subarray to select. -1 => all; 0 => 1.
BIF........First IF to plot
EIF........Last IF to plot.
BCHAN......Include only flags involving channels that overlap the
range from BCHAN to
ECHAN......ECHAN. BCHAN=0 -> 1, ECHAN=0 => max channel
ANTENNAS...A list of the antennas forming baselines. All 0 => all.
If any number is negative then the baselines are NOT to be
plotted and all others are.
BASELINE...A list of the baseliness with antennas given in ANTENNAS
to be plotted. All 0 => all. If any
number is negative then the baselines are NOT to be
plotted and all others are.
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.
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.
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.
