Usage for plotPWVFromASDM

Return to directory of Todd's CASA extensions

Read and plot the PWV values from the ASDM via the CalWVR.xml table. With this function, if you did not import the ASDM tables with importasdm, you can still plot the PWV vs. time from TelCal from the ASDM. By default, the median over antennas over 30 second time intervals is plotted. Setting showmedian=False will show every data point.


au.plotPWVFromASDM(asdm='', figfile=False, showMedianOnly=False, avgtime=30.0, meanelev=-1, 
                   freq=-1, station=1, linetype='.-', markersize=9, bandwidth=1.0, panels=1, 
  • figfile: Boolean, or a string (default filename = 'asdm.pwv.png')
  • showMedianOnly: show median only (True), or with all antennas colorized (False)
  • avgtime: time window over which to bin the PWV data
  • meanelev: compute the PWV at this specified elevation by scaling from zenith
    • freq: compute the transmission at this frequency at meanelev (GHz or string with units)
    • station: the weather station to use to compute transmission
    • bandwidth: the bandwidth to use to compute transmission (GHz or string with units)
  • linetype: to use on the showMedianOnly=True plot
  • markersize: of plotted points
  • panels: if 1, then PWV vs. time, if 2, then also plot PWV vs. height
  • plotrange: used for the second panel only
