DESCRIPTION

WBPLT is a program used to analyse wbcorr data.  

PARAMETERS

vis
The input visibility datasets. Several datasets can be given.
select
Standard visibility selection. See help on "select" for more information.
stokes
Normal Stokes/polarization selection. The default is to process all parallel-hand polarisation.
inc
Visibility increment (default is 1)
chans
A pair of values giving the range of channels to be plotted.
calfile
wbcorr lag-based calibration file.
bpfile
wbcorr frequency-based calibration file.
calfac
Factor to convert flux scale to Jy. Applied in addition to any calibration tables. Default = 1.0
xrange
X-axis range for plot. The default is to self-scale. The units are Jy for flux density, hrs for time ,and RA and degrees for DEC and phase.
yrange
Y-axis range for plot. The default is to self-scale. The units are Jy for flux density, hrs for time, and RA and degrees for DEC and phase.
axis
For plotting. Two values (minimum match active), one for each of the x and y axes chosen from:
 time                     [DD HH MM SS.S format]
 amplitude, real, imag    [natural units; Jy]
 phase                    [degrees]
 closure                  [degrees] - needs 3 baselines
 triple                   [natural units; Jy] - needs 3 baselines
 ra                       [HH MM SS.S format]
 dec                      [DD MM SS.S format]
 lst                      [HH MM SS.S format]
 hangle                   [HH MM SS.S format]
 systemp1 (geometric mean systemp - IF1 all antennas) [Jy]
 systemp2 (geometric mean systemp - IF2 all antennas) [Jy]
Defaults are axis=time,amp (x and y axes).
device
Standard PGPLOT device. See the help on "device" for more information.
log
Write ascii data to this log file. Format is specified in comment line. Maximum 9 channels. Default is no output file.
lags
A pair of values giving the range of lags to be plotted if options=dofft. There are 2n-2 lag channels starting at 0 and ending at 2n-3.
mask
Don't plot a value if the amplitude (not necessarly the yaxis) is within this pair of values.
options
nocal Do not perform gain calibration. nopol Do not perform polarisation calibration on the data. nopass Do not perform bandpass calibration on the data. relax Plots flagged data (only works if data not averaged in
          frequency with the line parameter) or data without
          valid positions.
stats Calculate some rudimentary statistics on y-values dtrack Switch on delay tracking for beam centre (i.e. non-
          meridian scans). wbcorr only!
dofft Transform frequency channels into lag channels before
          plotting. All frequency channels should be read in 
          (NB. lag spectrum is a real quantity)
lagwt For options=dofft or if calfile is set, this applies
          a triangular weight function to the lag domain
flag0 Filter on channel 0 for wbcorr data avall Average all frequency channels
