Usage for plotTrx

Return to directory of Todd's CASA extensions

Plot the Trx from the SYSCAL table of the specified ALMA ms, and save as png files. Can produce a multi-page pdf. See also plotTsys and plotTsky.

au.plotTrx(vis='', antenna = '', spw='', xaxis='freq', gs='gs',
             buildpdf=False, interactive=True, overlay='',
             plotrange=[0,0,0,0],pol='', figfile='', renumber=False, 
             replace={}, showatm=False, scan='', verbose=False,
             fontsize=12, doplot=True, atmcal=None, returnMeans=False,
             grid=True, warndiff=0.25, cleanup=True, 
             returnFracDiff=False, chanrange='92.1875%')
Options:
  • xaxis: 'freq' (default) or 'chan'
  • gs: full path to ghostscript's gs (if not found automatically)
  • antenna: a single antenna ID (as integer or string) or name
  • overlay: '' or 'antenna'
  • pol: '' or 'X' only or 'Y' only
  • figfile: '' (no png produced) or filename to write
  • buildpdf: True or False
  • interactive: True or False
  • plotrange: [xmin, xmax, ymin, ymax]
  • renumber: renumbers the spws to start at 0, in the original order (9,11,13,15-->0,1,2,3)
  • replace: provide a dictionary for the renumbering, e.g. {9:0, 11:1, 13:2, 15:3}
  • showatm: overlay atmospheric transmission
  • scan: limit the result to this single scan
  • verbose: if True, then print the median values for spw/antenna/pol
  • fontsize: of the tick labels and axis labels (default = 12)
  • doplot: if False, then don't plot anything, just return the medians
  • atmcal: an instance of class Atmcal; if None, then run Atmcal if False, then first try the faster, less robust method
  • grid: draw dotted grid lines at the major tick marks of the plot
  • warndiff: if the two pols differ by this fraction, print a warning
  • cleanup: remove pngs and single page PDFs (only used if buildpdf==True)
  • returnFracDiff: if True, return a dictionary describing warndiff
  • chanrange: use this percentage of central channels to autoscale the y-axis
Returns:
  • a dictionary keyed by spw ID, with values = median
  • the Atmcal instance
  • a dictionary with values = means (if returnMeans==True)
  • a dictionary with values = percentage greater than warndiff (if returnFracDiff==True)
