The name of the input uv data sets. Several can be given (wild
cards are supported). No default.
The normal uv selection commands. The default is plot everything.
The normal uv linetype in the form:
The default is all channels (or all wide channels if there are no
The Stokes/polarization types to be plotted. The default is to
plot those polarizations present in the input files.
Time averaging interval, in minutes. The default is 0 (i.e. no
Hanning smoothing width (an odd integer). Smoothing is
applied after averaging. Default is 1 (no Hanning smoothing).
An offset (in arcsec) to shift the data. Positive values result in
the data center being shifted to the North and East. Two values
should be given, being the shift in the RA and DEC directions.
The default is 0,0 (i.e. no shift).
This gives extra processing options. Several options can be given,
each separated by commas. They may be abbreviated to the minimum
needed to avoid ambiguity. Possible options are:
'nocal' Do not apply the gains file. By default, SmaUVSPEC
applies the gains file in copying the data.
'nopass' Do not apply bandpass corrections. By default,
SmaUVSPEC corrects for the bandpass shape if the
required information is available.
'nopol' Do not apply polarizatiopn corrections. By default
SmaUVSPEC corrects for polarization corss-talk.
'ampscalar' When plotting amplitude, this causes it to perform
scalar averaging. By default it does vector averaging.
'rms' When plotting amplitude, this causes it to plot
the rms amplitude. by default it does vector averaging.
'nobase' Plot all the baselines on one plot.
'avall' Average all the baselines together before plotting.
'dots' Plot phases with dots instead of filled circles.
'flagged' Plot flagged data instead of unflagged data. The
default is to plot only unflagged data.
'all' Plot both flagged and unflagged data.
'jplcat' Plot JPL catalog lines. The xaxis and yaxis are
then forced to be frequency and ampltiude.
'restfreq' plot the frequency in the source rest frame
when using the JPL catalog (options=jplcat is chosen.)
Default is to plot the sky frequency.
This gives the path of JPL catalog. No Default. When script
$MIR/install/get_jplcatalog is used to install the JPL catalog,
the path of JPL catalog is assigned to: $MIRCAT/jplcat/;
otherwise, it can be specified by users.
The radial velocity of source in km/s w.r.t. the LSR or
the barycenter. The velocity reference frame is given
in veltype. Positive velocity is away from observer.
Default is zero.
This gives the reference frame. Either the LSR or the BARY
(barycenter) is supported. The default is the one defined
in the uv data.
This is the velocity definition used in the shift of the catalog lines.
radio is the radio definition.
optic is the optical definition.
relat is the special relativistic expressions.
The default is "radio".
This is the common log of the minimum strength in the JPL catalog units.
The default is -500.
This gives two strings, which determine the X and Y axes of each plot.
The values can be abbreviated to uniqueness.
Possible values for the X axis are:
channel X-axis is channel number.
frequency X-axis is the sky frequency, in GHz.
dfrequency X-axis is the Doppler-corrected frequency, in GHz.
velocity X-axis is velocity in radio convention, in km/sec.
felocity X-axis is velocity in optical convention, in km/sec.
lag X-axis is lag number.
Possible values for the Y axis are:
amplitude Plot amplitude.
phase Plot phase.
real Plot real part of the data.
imaginary Plot imaginary part of the data.
both Plot both amplitude and phase.
The default is axis=channel,amplitude.
The min and max range along the y axis of the plots. The default
is to autoscale.
Note: in the case of yaxis=both, the range is specified by the
yrange to the variable amplitude. The phase is plotted below
the amplitude in the bottom panel with the range from -180 to
Allows users to choose a symbol (dot) size in a range between
1-201. The actual plotted dot size depends on the device
resolution. Other internal symbol selecting function
would be failed when this parameter is in use.
Default is to disable this function.
Allow users to choose single title content with two characters:
title = BL -> Baseline label;
= PO -> Polarization label;
= TI -> Time label;
= IN -> Time interval.
And the font size for the title and the axis labelling would be
enlarged by a factor of 1.5.
Default is for labelling all the information above.
PGPLOT plot device/type. No default.
Number of plots in the x and y directions. The default is
determined from the number of antennae in the data-sets.
Log file into which the spectra are dumped in the order in which
they are plotted. Really only useful if your plot is quite simple.
