Usage for plotTcal

Return to directory of Todd's CASA extensions

Plot either the Tsys, Trx or Tsky from the SYSCAL table of the specified ALMA ms, and save as png files. Can produce a multi-page pdf. See the wrapper functions: plotTsys, plotTrx, and plotTsky. See also readTcal for reading them from the ASDM.


au.plotTcal(vis='', antenna = '', spw='', xaxis='freq', t='tsys', 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=False, warndiff=0.5, cleanup=True, returnFracDiff=False,
  • t: 'tsys' (default), 'trx' or 'tsky'
  • 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 median for each 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
