HELP SECTION
ANBPL
Type: Task
Use: Plots and or prints data from a u,v data base making a plot file
or TV plot and/or a printer output. The data are converted to
antenna-based form before plotting or printing. Plotting is
done one antenna per plot with the number of plots per page
specified by NPLOTS. The plots are written one page per plot
file so in general several plot files will be created (if DOTV
is false).
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.
SOURCES....Source list. If the data is a multi-source file
ANBPL will plot the visibility for the first
source specified. If the data is a single
source file no source name need be specified.
QUAL.......Only sources with a source qualifier number in the
SU table matching QUAL will be used if QUAL is not
-1.
CALCODE....Calibrators may be selected on the basis of the
calibrator code:
' ' => any calibrator code selected
'* ' => any non blank code (cal. only)
'-CAL' => blank codes only (no calibrators)
anything else = calibrator code to select.
NB: The CALCODE test is applied in addition to the
other tests, i.e. CALSOUR and QUAL, in the
selection of sources for which to determine
solutions.
SELBAND....Bandwidth of data to be selected. If more than
one IF is present SELBAND is the width of the
first IF required. Units = kHz, 0=> all
SELFREQ....Frequency of data to be selected. If more than
one IF is present SELFREQ is the frequency of the
first IF required. Units = MHz, 0=> all
FREQID.....Frequency identifier to select (you may determine
which is applicable from the OPTYPE='SCAN' listing
produced by LISTR. If either SELBAND or SELFREQ
are set their values overide that of FREQID,
however setting SELBAND and SELFREQ may occasionally
result in an ambiguity, in which case the task will
request that you use FREQID.
BCHAN......Start channel. 0 => 1
ECHAN......End channel. 0 => BCHAN
If BCHAN and ECHAN are set specificially then the
data will be spectrally averaged across the range
BCHAN -> ECHAN before being plotted.
BIF........Start IF number to plot. 0 => 1
EIF........End IF number to plot. 0 => highest
AVGIF......> 0 => IFs BIF through EIF will be averaged before
plotting, otherwise they will be plotted separately.
XINC.......Plot every XINC'th visibility
which might be plotted. 0 => 1
UVRANGE....Range (min, max) of projected baselines to include
0,0 => all baselines
TIMERANG...The specified time range.
1 = Start IAT day (day 0 = first day in data base)
2 = Start IAT hour
3 = Start IAT minute
4 = Start IAT second
5 = Stop IAT day (day 0 = first day in data base)
6 = Stop IAT hour
7 = Stop IAT minute
8 = Stop IAT second
stop IAT = 0 => beginning
stop IAT = 0 => end.
of time.
Note that multi-subarray data are separated by 5 days for each
subsequent subarray if the data are DBCON's output.
ANBPL does not remove this time shift starting May 1, 2001.
So pay attention on this fact selecting the TIMERANG.
STOKES.....Specifies the stokes type(s) to be plotted:
Recognized values are 'I', 'Q', 'U', 'V', 'IV', 'IQU',
'IQUV' 'RR', 'LL', 'LR', 'RL', 'RRLL', 'HALF', 'FULL'
' ' => 'HALF' = 'RRLL'
ANTENNAS...A list of the antennas to be plotted.
BASELINE...Baselines between antennas named in ANTENNAS and those
named in BASELINE are selected.. There are four possible
combinations of ANTENNAS and BASELINE:
1. ANTENNAS = 0; BASELINE = 0.
All possible baselines are selected.
2. ANTENNAS <>0; BASELINE = 0.
a)All ANTENNAS > 0
Baselines including an antenna in the ANTENNAS list
are selected;
b)Some ANTENNAS < 0
All baselines NOT including an antenna in the ANTENNAS
list are selected;
3. ANTENNAS = 0; BASELINE <> 0.
a)All BASELINE > 0
Baselines including an antenna in the BASELINE list
are selected;
b)Some BASELINE < 0
All baselines NOT including an antenna in the BASELINE
list are selected;
4. ANTENNAS <> 0; BASELINE <> 0.
a)All ANTENNAS>0 and all BASELINE>0
Baselines between antennas named in ANTENNAS and those
named in BASELINE are selected.
b)Some ANTENNAS<0 .OR. some BASELINE<0
Baselines between antennas named in ANTENNAS and
those named in BASELINE are DE-selected, all others
are selected.
DOCALIB....If true (>0), calibrate the data using information in the
specified Cal (CL) table for multi-source or SN table for
single-source data. Also calibrate the weights unless
DOCALIB > 99 (use this for old non-physical weights).
GAINUSE....version number of the CL table to apply to
multisource files or the SN table for single
source files. 0 => highest.
DOPOL......If > 0 then correct data for instrumental polarization as
represented in the AN or PD table. This correction is
only useful if PCAL has been run or feed polarization
parameters have been otherwise obtained. See HELP DOPOL
for available correction modes: 1 is normal, 2 and 3 are
for VLBI. 1-3 use a PD table if available; 6, 7, 8 are
the same but use the AN (continuum solution) even if a PD
table is present.
PDVER......PD table to apply if PCAL was run with SPECTRAL true and
0 < DOPOL < 6. <= 0 => highest.
BLVER......Version number of the baseline based calibration
(BL) table to appply. <0 => apply no BL table,
0 => highest.
FLAGVER....specifies the version of the flagging table to be
applied.
0 => highest numbered table.
<0 => no flagging to be applied.
If APARM(1)>0 then
if FLAGVER>0 => the specified table is copied to
the next highest version and recognized bad points
are added to this table
if FLAGVER=0 => the highest numbered table is copied
to the next highest version and recognized bad
points are added to this table
if FLAGVER<0 => Recognized bad points
are recorded in a new FG table
DOBAND.....If true (>0) then correct the data for the shape of the
antenna bandpasses using the BP table specified by BPVER.
The correction has five modes:
(a) if DOBAND=1 all entries for an antenna in the table
are averaged together before correcting the data.
(b) if DOBAND=2 the entry nearest in time (including
solution weights) is used to correct the data.
(c) if DOBAND=3 the table entries are interpolated in
time (using solution weights) and the data are then
corrected.
(d) if DOBAND=4 the entry nearest in time (ignoring
solution weights) is used to correct the data.
(e) if DOBAND=5 the table entries are interpolated in
time (ignoring solution weights) and the data are then
corrected.
BPVER......Specifies the version of the BP table to be applied
0 => highest numbered table.
<0 => no bandpass correction to be applied.
SMOOTH.....Specifies the type of spectral smoothing to be applied to
a uv database . The default is not to apply any smoothing.
The elements of SMOOTH are as follows:
SMOOTH(1) = type of smoothing to apply: 0 => no smoothing
To smooth before applying bandpass calibration
1 => Hanning, 2 => Gaussian, 3 => Boxcar, 4 => Sinc
To smooth after applying bandpass calibration
5 => Hanning, 6 => Gaussian, 7 => Boxcar, 8 => Sinc
SMOOTH(2) = the "diameter" of the function, i.e. width
between first nulls of Hanning triangle and sinc
function, FWHM of Gaussian, width of Boxcar. Defaults
(if < 0.1) are 4, 2, 2 and 3 channels for SMOOTH(1) =
1 - 4 and 5 - 8, resp.
SMOOTH(3) = the diameter over which the convolving
function has value - in channels. Defaults: 1,3,1,4
times SMOOTH(2) used when input SMOOTH(3) < net
SMOOTH(2).
SUBARRAY...The subarray number desired. 0=> 1.
To have all subarrays plotted, give -1. Be aware that the
station names and model plotted will be for subarray 1
only.
SOLINT.....Time over which to pre-average data before
plotting (mins). =0 => no pre-averaging.
If SOLINT<0 then SOLINT = ABS(SOLINT) and averaging does
not pay attention on scans
If SOLINT>0 then averaging pays attention on scans.
SOLINT = MIN(SOLINT, SCAN)
If ABS(SOLINT)>0 then
X can be only time;
Y can be only amp, phas, real, imag, weight or rms
DO3COLOR...> 0 => plot the separate IFs and/or polarizations in
different colors if they occur in the same panel.
<=0 => otherwise they are done in the same color.
The color scheme is
COLOR = 0
DO IF = 1,Nif
DO POL = 1,Npol
set and use COLOR
COLOR = COLOR + DeltaColor
END DO POL
END DO IF
where COLOR=0 is pure RED, DeltaColor is set so that the
last value of COLOR is 1 which is pure BLUE. Npol is the
number of requested polarizations (1 unless OPCODE is
ALSI or ALST) and Nif is the number of IFs plotted in the
panel (1 unless OPCODE is ALIF or ALSI, then BIF to EIF)
Thus, if there are 4 IFs and one polarization, the plot
will be of red, yellow, cyan, and blue for IFs 1 through
4, resp. If there are 2 IFs and 2 polarizations (RR and
LL say), then red is RR in IF 1, yellow is LL in IF 1,
cyan is RR in IF 2, and blue is LL in IF 2. Note that
the blue is plotted after the red and so may overlap and
obscure the red.
OPCODE.....Type of plot:
'ALIF' => will plot data for all IFs (BIF through EIF) on
a single plot (antennas and polarizations are
plotted separately).
'ALST' => will plot data for both polarizations (RR and
LL) on a single plot (antennas and IFs are plotted
separately).
'ALSI' => will plot data for both polarizations (RR and
LL) and all IFs (BIF through EIF) on a single plot
(antennas are plotted separately).
other => will plot each request polarization, each
requested IF and each each requested antennas
individually looping in that order.
BPARM......Control parameters:
1 = type of X-axis ( other => 2
1 = time (IAT)
2 = time (IAT hms),
3 = source number,
4 = hour angle (hours)
5 = elevation (degrees)
6 = azimuth (degrees)
7 = parallactic angle (deg)
Moving sources are supported for types 4-7 if there is a
PO table
2 = type of Y-axis (as above). other => 12
11 = amplitude (antenna based amplitude)
12 = amplitude (antenna based complex, amplitude value)
13 = phase, (antenna based complex)
14 = phase (antenna-based complex normalized)
15 = real part (antenna based complex)
16 = imaginary part (antenna based complex)
17 = weight
If <0 => Both Amplitude and phase are plotted.
3 = if greater than zero, use BPARM(4) - BPARM(8) as the
ranges of the axes. If less than zero, use the BPARMs
to limit the range of the axes, but self-scale the axes
within that range. If 0.0, scale the Y axis separately
for each baseline.
4 = Minimum of X-axis. See note below on units.
5 = Maximum of X-axis (if = BPARM(4) do self-scale in X).
6 = Minimum of Y-axis. See note below on units.
7 = Maximum of Y-axis (if = BPARM(6) do self-scale in Y).
8 = Minimum of phase (amp+phase). See note below on units.
9 = Maximum of phase (amp+phase) (if = BPARM(8) do self-scale in
phase).
10 : > 0 scalar average
= 0 vector average
Units to use in BPARM(4) - BPARM(9):
axis type = 11, 12, 15, 16 Jy
13, 14, 5, 6, 7 Degrees
2 Days from start of observation
1, 4 Hours
The axes will be labeled in appropriately scaled units, with axis
types 11 and 12 expressed in sexagesimal (hours, minutes, seconds as
needed). NOTE: two models will be plotted if the x axis type is 3,
6, 7, or 8 (uv distance, u, v, w) since the x axis value determines
the baseline only with an ambiguity. Models are plotted only if the
y-axis type is 1, 2, 9, or 10 and the x-axis type is NOT 1, 2, 9, or
10 (and if NITER > 0 and there is an appropriate CC file).
NPLOTS......Max number of plots per page. 0 => 3. If AMP and
PHASE are plotted together (BPARM(2) < 0), NPLOTS
equals max. number of pairs of plots per page.
SYMBOL......Symbol to use when plotting.
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 the plotted symbol. 0 -> 1
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.
DOCRT.......0 -> Do no printer display
BPARM(1) must be 1 or 2 as well to get printer output.
False (< 0) use the line printer if OUTPRINT = ' '
else write named OUTPRINT file only. When OUTPRINT
is not blank, DOCRT=-2 suppresses the page-feed
character on page headers and DOCRT=-3 suppresses
page headers and most other header information.
When OUTPRINT is blank, the line printer will be
used. ANBPL now counts the lines to be printed
before printing any and asks for permission to
continue if the count > 500.
True (> 0) use the terminal interactively. The task
will use the actual terminal width as a display limit
unless 72 < DOCRT < width. In that case, the display
limit will be DOCRT characters.
OUTPRINT....Disk file name in which to save the line printer output.
' ' => use scratch and print immediately for interactive
jobs - batch jobs use OUTPRINT = 'PRTFIL:BATCHjjj.nnn'
(jjj= job #, nnn = user #). When OUTPRINT is not blank,
multiple outputs are concatenated, and the file is not
actually printed.
NDIG........Number of digits in the display: 3 to 8.
BADDISK....The disk numbers to avoid for scratch files (sorting
tables mostly).
