AIPS HELP file for BPEPL in 31DEC21
As of Sun May 16 12:42:14 2021
BPEPL: plot bandpass table overlaying multiple times like BPEDT
INNAME Input UV data (name)
INCLASS Input UV data (class)
INSEQ Input UV data (seq. #)
INDISK Input UV data disk drive #
INVERS Input table file version no.
FREQID -1.0 Frequency ID; 0 => 1
SUBARRAY 0.0 Subarray number 0 => 1.
TIMERANG Time range to include
BCHAN Lowest channel number
ECHAN Highest channel number
BIF First IF to include
EIF Last IF to include
ANTENNAS Antennas to include/exclude
DO3COLOR -1.0 2.0 > 0 => color times
< 0 black & white plot file
APARM Initial plot ranges for
(5) fraction for phase
(6) > 0 do image type plot
LTYPE -410.0 410.0 Type of labeling: 1 border,
2 no ticks, 3 standard, 4 rel
to center, 5 rel to subim cen
6 pixels, 7-10 as 3-6 with
only tick labels
<0 -> no date/time
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.
XYRATIO 0.0 X/Y ratio 0 -> fit TV or 1 PL
IMSIZE Size for grid plot when
APARM(6) > 0. 0 -> 1000
BADDISK Disks to avoid for scratch
Use: This task makes plots much like BPEDT but can put them in plot
files for later display rather than using the TV and
interactivity. The two polarizations are always plotted
INNAME.....Input UV data file (name). Standard defaults.
INCLASS....Input UV data file (class). Standard defaults.
INSEQ......Input UV data file (seq. #). 0 => highest.
INDISK.....Input UV data file disk drive #. 0 => any.
INVERS.....Input table file version number, 0 -> current highest.
The input file is not changed, but may be sorted.
FREQID.....Frequency ID to edit. 0 => 1.
SUBARRAY...Subarray number to edit. 0 => 1.
TIMERANG...Time range of the data to be edited. In order:
Start day, hour, min. sec, end day, hour, min. sec. Days
are relative to the reference date.
BIF........The lowest numbered IF to include. 0 => 1.
EIF........The highest numbered IF to include. 0 =>highest.
Note: not all data sets will have IFs.
ANTENNAS...A list of antenna numbers to include. 0 => all.
DO3COLOR...If DO3COL > 0, use 3 grey-scale image planes to plot the
data in colors so as to differentiate between times. The
first time is pure red, the last nearly pure blue. Blue
can overwrite the earlier times.
< 0 on plot files => make a black on white plot. Use
DOCOLOR <= 0 in LWPLA
= 0 on plot files, color plotted points with standard
color for GRCHAN (default = 4 = cyan). Any DOCOLOR
works in LWPLA.
> 0 on plot files plots points in suitable colors (as
above) on a black background. DOCOLOR > 0 in LWPLA
is needed to see labels.
APARM......Initial plot rnges - can change later
(1) Minimum amplitude plotted
(2) Maximum amplitude plotted (1) >= (2) self-scale
(3) Minimum phase (degrees) plotted
(4) Maximum phase plotted (3) >= (4) self-scale
(5) Fraction of vertical scale for phase. 0 -> 0.3
(6) > 0 => plot the bandpasses into memory and then
put the grid as an image onto the TV or the plot file.
If there are lots of times, this can be quite a
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.
IMSIZE.....If APARM(6) > 0 and DOTV <= 0, make the grid this size.
The default is 1000 x 1000. Note that is IMSIZE is larger
than your TV screen, then TVPL will not be able to plot.
LWPLA can handle any size.
BADDISK....The disk numbers to avoid for scratch files (sorting
