HELP SECTION
PDPLT
Type: Task
Use: Plots selected data versus frequency from a PD (spectral
polarization D term) table.
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......'PD' is assumed for now
INVERS.....Version number of table to plot, 0=>highest no.
IN2NAME....UV file name (name). Standard defaults.
Fill the 2 adverbs only if you want to compare
two different PD tables.
IN2CLASS...UV file name (class). Standard defaults.
IN2SEQ.....UV file name (seq. #). 0 => highest.
IN2DISK....Disk unit #. 0 => any.
IN2VERS....Version number of table to plot, 0=>highest no.
IN3NAME....UV file name (name). Standard defaults.
Fill the 3 adverbs only if you want to compare
three different PD tables.
IN3CLASS...UV file name (class). Standard defaults.
IN3SEQ.....UV file name (seq. #). 0 => highest.
IN3DISK....Disk unit #. 0 => any.
IN3VERS....Version number of table to plot, 0=>highest no.
IN4NAME....UV file name (name). Standard defaults.
Fill the 4 adverbs only if you want to compare
four different PD tables.
IN4CLASS...UV file name (class). Standard defaults.
IN4SEQ.....UV file name (seq. #). 0 => highest.
IN4DISK....Disk unit #. 0 => any.
IN4VERS....Version number of table to plot, 0=>highest no.
ANTENNAS...A list of the antennas to be plotted. All 0 => all.
(The use of negative to omit is not done in this task.)
These antenna numbers apply to the first data set.
BPARM......A list of antenna numbers in the second data set where
BPARM(i) corresponds to ANTENNAS(i). If BPARM(1) is
zero, ANTENNAS is used for the second data set.
CPARM......A list of antenna numbers in the third data set where
CPARM(i) corresponds to ANTENNAS(i). If CPARM(1) is
zero, ANTENNAS is used for the third data set.
DPARM......A list of antenna numbers in the fourth data set where
DPARM(i) corresponds to ANTENNAS(i). If DPARM(1) is
zero, ANTENNAS is used for the fourth data set.
FREQID.....Frequency identifier to select (you may determine which is
applicable from a PRTAB on the PD table)
SUBARRAY...Limit display to specific subarray. 0 -> 1.
STOKES.....The desired Stokes type of the displayed data:
'R' = RCP, 'L' = LCP, 'RL' or 'RRLL' both RCP and LCP
'V' = VLP, 'H' = HLP, 'VH' or 'VVHH' both VLP and HLP
BIF........First IF IF to plot
EIF........Last IF to plot.
OPTYPE.....Data to be plotted:
1. 'PHAS' = phase,
2. 'AMP ' = amplitude,
3. 'A&P ' = both together
PIXRANGE...If PIXR(1) < PIXR(2), all plots will be from PIXR(1) to
PIXR(2) (amplitude, phase, or in A&P, amplitude).
Otherwise each plot will be self-scaling.
APARM......(1) For A&P, if APARM(1) < APARM(2), use these to control
the phase plot range.
(3) If > 0, plot frequency labels on the x axis
If the 2 files have different frequencies then this
option is forced as is APARM(4) and no divider is
plotted.
(4) If > 0, omit IF dividers. A divider without ticks
will still be plotted if there is a discontinuity in
the frequency axis.
DO3COLOR...<= 0 => use line type 4 for all points plotted.
> 0 => use 3-color to separate antennas
> 1.5 => use 3-color to separate each antenna in ANTENNAS
but use the same color for BPARM(i), CPARM(i),
and DPARM(i) as is used for ANTENNAS(i).
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. To have
no points plotted, set -0.2 <=FACTOR < 0.
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.
