Use: Prints information in a uv data base in a variety of possible
forms. Numerous selection criteria are available and
calibration and flagging may optionally be applied.
LISTR will work on multi-source, indexed files or TB sorted
single-source files in some modes.
Not all adverbs apply to all types of listing; the
following notes when an adverb is used for only some listing
types or its useage depends on the type.
Note that all listings can scale both phases and
amplitudes - check the scaling shown at the beginning of each
data section carefully.
Two special GAIN listing forms have been added: EFST and
SEFD. For these to appear as claimed, the visibility data must
have been loaded as correlation coefficients, the calibrator
sources must be unresolved, and the flux densities of the
calibrator sources must be known. See EVLA Memo 119.
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.
OPTYPE.....Type of listing desired:
'SCAN'=scan and source summary,
'MATX'=scan averaged (or shorter) maxtix listing,
' ' or unrecognized => 'MATX'
'LIST'=column listing of selected baselines,
'GAIN'=column listing of gains from SN, CL, TY, or SY
'EFST'=column listing of SN or CL table converted to
Tsys/efficiency in degrees K. Is amplitude gain
squared and then multiplied by 36.8.
'SEFD'=column listing of SN or CL table converted to the
flux density which doubles the system temperature
in Jy. Is amplitude gain squared and then
multiplied by 206.
For EFST and SEFD to be what is desired, the visibility
data must have been loaded as correlation coefficients,
the calibrator sources must be unresolved, and the flux
densities of the calibrator sources must be known. See
EVLA Memo 119. Note that these are scaled for the VLA
(25m antennas) only.
INEXT......SN, CL, TY, or SY table type to list, ' '=> SN. 'GAIN'
INVERS.....SN, CL, TY, or SY table version number. 0=highest.
SOURCES....List of sources to be listed. ' '=> all; if any
starts with a '-' then all except ANY source named.
For OPTYPE='GAIN' this controls the sources in the
SN, CL or TY table to be listed.
CALCODE....Calibrators may be selected on the basis of the
calibrator code given in the SU table.
' ' => 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 selection tests
TIMERANG...Time range of the data to be listed. In order:
Start day, hour, min. sec,
end day, hour, min. sec. Days relative to ref.
STOKES.....The desired Stokes type of the listed data:
'HALF' (=RR,LL) or I are currently supported.
' ' => leave the data in its original form,
or RR and LL if both exist.
'POL ' => RL, LR
'POLC' => RL, Conjugate(LR); this is useful for
finding the Faraday rotation from known
OPTYPE='LIST': 'I','Q','U','V','RR','LL','RL', or
'RL'; anything else=>'I'
'R','L', 'I', 'HALF'=(R,L)
'POLD' => R/L (for phase differences and ampl.
anything else => 'HALF'
SELBAND....Bandwidth of data to be selected. If more than one IF is
present SELBAND is the width of the 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 result in an ambiguity. In that case the
task will request that you use FREQID. If neither
SELBAND, SELFREQ nor FREQID are specified then the first
FQ id in the FQ table (usually 1) will be used. FREQID
applies to GAIN listings, but if all 3 freq-id adverbs
are <= 0, then all freq-ids are listed.
BIF........Lowest IF to list. All operations will list the IFs one
at a time. 0 => 1.
NOTE to VLA users: IF=1 corresponds to the VLA
AC ifpairs and IF=2 corresponds to the BD ifpairs.
EIF........Highest IF to list. 0 => Highest
BCHAN......First channel to average. LIST and MATX will average
channels BCHAN through ECHAN. 0 => 1.
ECHAN......Last channel to average. 0 => highest.
ANTENNAS...A list of the antennas to list. If any number is
negative then all antenna numbers in ANTENNAS are NOT
desired and all others are. All 0 => list all.
Note that antenna numbers that do not appear in the
relevant antenna file(s) or which appear with a name
containing the string 'OUT' are not displayed.
BASELINE...Baselines are specified for the LIST option using
BASELINE. Eg. baselines 1-6,1-8, 2-6 and 2-8 use
UVRANGE....Range of projected spacings to be listed in 1000's
of wavelengths. 0 => 1, 1.E10
SUBARRAY...Subarray number to list. <1 => 1 for all OPTYPEs except
GAIN; < 1 => all subarrays for GAIN listings only.
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 Cal. table to apply to the
data if DOCALIB=1. Refers to a CL table for
multisource data of an SN table for single source.
0 => highest. Used for OPTYPE='MATX','LIST'.
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.
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
(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
BPVER......Specifies the version of the BP table to be applied.
<0 => no bandpass correction done.
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
XINC.......Display only every XINC'th line in LIST and GAIN
displays. 0 -> 1,
1) controls the type of information to be printed:
0 => amplitude,
1 => phase,
2 => RMS of amplitude,
3 => amplitude + amplitude rms (MATX)
4 = phase + phase rms (MATX)
5 = amplitude and phase (MATX)
6 = delay (GAIN)
7 = rate (GAIN)
8 = SNR (i.e. weight) (GAIN)
9 = parallactic angle (GAIN) including planets
10 = System temperature (GAIN)
(for VLA nominal sensitivity)
11 = source elevation (GAIN) including planets
12 = multiband delay (GAIN)
13 = Antenna temperature (GAIN)
(for VLA back-end or front-end syste, temperature
depending on FILLM settings)
14 = Data weight (MATX)
15 = Psys = Psum/Pdif/2 * Tcal
16 = Pgain = Pdif/Tcal
17 = Pdif
18 = Psum
19 = Post Detector Gain
20 = Source Azimuth including planets
21 = Source Hour angle including planets
Types 9, 11, 20, and 21 support moving sources if
there is a PO table.
2) controls the type of averaging:
0 => vector average,
1 => amp scalar averaging. Amplitudes and phases
3) The number of digits per column for column
based listings. The allowed range is 4 to 10;
4 will be used if the value is outside of the
4) Averaging time in min. to be used for MATX or
0=> scan average (MATX multi source files)
0=> 10 min. (MATX single source files)
0=> 0 in LIST - times that are only subtly different
are taken as different and displayed on separate
lines. On-line and later averaging can cause such
subtle time differences. SET THIS ADVERB for LIST.
large=>scan average. (MATX, LIST)
5) Type of listings for OPTYE='GAIN':
0=> list gain solutions in the style of the
DEC-10/ISIS packages, i.e long lists of numbers
with a constant scale for all.
1=> Scale each scan/source separately and provide a
scan summary between each scan.
Default = 0
6) Matrix scaling control:
0=> when plotting amplitude matrix followed by rms,
use the scale factor from the amplitude matrix to
scale the rms.
1=> self-scale each matrix separately.
7) > 0 => self-scale phases, otherwise they are in
integer degrees scaled by FACTOR.
8) > 0 on 'LIST' => list each baseline twice so that e.g.
baseline 3-23 will appear with all the other 3-*
baselines and with all other *-23 baselines. By
default 3-23 appears with the 3's but at the 23's only
23-24, 23-25, etc. are displayed.
9) > 0 => times are displayed as LSTs not IAT or UTC
10) > 0 sets the value of a print of 1 in whatever units
are being printed. For DPARM(1)=5, DPARM(10) applies
to the amp part and phase is in integer degrees.
DOACOR.....> 0 => include autocorrelation data.
FACTOR.....The default for gain listings is to take the scale
derived from the first record printed and apply it to all
subsequent records. However this is obviously not a good
idea in all cases. If you are not satisfied with this
default value, you can use FACTOR to multiply the scale
factor derived and then rerun LISTR printing the rescaled
values. Note: a FACTOR of 0.1 makes all the numbers
printed (integers) 10 times larger. Thus a display in
integer degrees of phase or angle becomes a display in
integer 0.1 degrees.
DOCRT......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. LISTR 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
BADDISK....Disk numbers to avoid for scratch files. Scratch
files may be created by the sorting routines if
calibration or flagging is applied.
LISTR: Task to list uv data.
DOCUMENTOR: Bill Cotton NRAO/CV
RELATED PROGRAMS: UVFLG
LISTR is designed to display uv data in line printer
listing form as an aid in evaluating and editing data; several
methods of displaying the data are provided. LISTR should work
in at least some form on both single and multi-source data
The standard adverbs for calibration and editing e.g.
applying CL, BL and FG tables to the data etc.) are provided.
OPTYPE='MATX' requests a scan averaged matrix listing. Pairs of
polarizations can be listed simultaneously:
RR, LL if both exist and STOKES= 'HALF' or STOKES= ' ';
RL, LR if both exist and STOKES= 'POL '
RL, conjugate(LR) if both exist and STOKES= 'POLC'
Or one polarisation can be listed:
RR if it exists and STOKES = 'RR ' or
RR is the only one and STOKES = ' '.
LL if it exists and STOKES = 'LL ' or
LL is the only one and STOKES = ' '.
Two (one) lines under matrix correspond to auto correlation.
Only a single IF or frequency channel may be specified.
An averaging time shorter than a scan may be requested using DPARM(4).
Note: scans are not defined for single source data.
OPTYPE='LIST' requests column listings of selected baselines.
The time will be averaged as specified by DPARM(4). Only a single
polarization can be listed but all frequencies and IF selected will be
averaged. A scan heading is given each time a new scan is
OPTYPE='GAIN' requests column listings of selected contents of
the CL, SN or TY table specified by INEXT and version number INVERS.
The type of data (amplitude, phase, delay, rate) listed is controlled
by DPARM(1). Multiple IFs and/or polarizations may be listed in a
single execution. STOKES='POLD' will tabulate R-L phase differences or
R/L amplitude gain ratios, if amplitude or phase is selected as
DPARM(1). This polarization option is ignored for other quantities.
OPTYPE='SCAN' requests scan and source summaries.
ANTENNAS and BASELINE:
The matrix option allows selection of data by antenna
only. All baselines between the antennas given in ANTENNAS
will be displayed.
The column listing option allows selection of data by
baseline; this involves both ANTENNAS and BASELINE. The
baselines selected are those between antenna listed in ANTENNAS
and those in BASELINE. All zeroes in either of these arrays
imply all altennas.
specifies baseline 1-10 ( the zeroes are necessary to prevent
specifying the same baseline a large number of times).
1-3,1-4,1-5,1-6,1-3,2-4,2-5,2-6,3-4,3-5,3-6,4-5 and 4-6.
Listings of antenna gain solutions (GAIN) will only
contain antennas specified by ANTENNAS.
(1) specifies the type of information to be listed:
0 => amplitude of the visibility,
1 => phase of the visibility,
2 => RMS of the amplitude of the visibility (enough time
samples must be included to compute an RMS),
3 => Amplitude + RMS (OPTYPE=MATX),
4 => phase + RMS (of amplitude) (OPTYPE=MATX),
5 => amplitude and phase (OPTYPE=MATX),
6 => delay (OPTYPE=GAIN),
7 => rate (OPTYPE=GAIN),
8 => SNR, actually the solution "WEIGHT" (OPTYPE=GAIN).
9 => Parallactic angle of the antenna at the time of the
gain record (OPTYPE=GAIN)
10 => System temperature of the antenna (OPTYPE=GAIN)
11 => Source elevation (OPTYPE='GAIN')
12 => Multiband delay (OPTYPE='GAIN')
(2) specifies the type of averaging:
0 => vector averaging of the selected visibilities before
conversion to amplitude or phase.
1 => "amp-scalar" averaging; amplitudes and phases are
computed for the individual visibilities and averaged.
(3) specifies the number of digits per column in the output to
be used for each value listed. The allowed range is 4 to 10;
if a number outside of this range is given, 4 is used. A
smaller number of columns per value allows more values to
be listed but with lower precision.
(4) specifies the averaging time to be used for the MATX or
LIST options. Visibilities are averaged by the specified
method for DPARM(4) min. Zero implies the integration time
of the input data (LIST) or scan averages (MATX) and a
large time will be truncated at the end of each scan.
(5) Type of listings for OPTYE='GAIN':
There are two formats of listing available when listing
gain solutions: one (the default) applies a constant
gain factor to all values (this is under user control),
and the output is similar to that produced by the old
Dec-10 programs. The other scales each scan separately
when producing the output.
0=> list gain solutions in the style of the
DEC-10/ISIS packages, i.e long lists of
numbers with a constant scale for all.
1=> Scale each scan/source separately and
provide a scan summary between each scan.
Default = 0
(6) Matrix scaling control:
0=> when plotting amplitude matrix followed
by rms, use the scale factor from the amplitude
matrix to scale the rms.
1=> self-scale each matrix seperately.
Default = 0
