Continuum polarimetry case

In the calibrater tool, transfer the flux scale calculated for 3C 286 to the gain calibrator, 0917+624, and write the scaled solutions to a file on disk called ap366.fluxcal. Plot the solutions with the plotcal function (Fig. 1.14):

calC.fluxscale(tablein='ap366.gcal',      # Transfer the flux density scale 
               tableout='ap366.fluxcal',  #  from 1328+307 (B1950: 3C286)
               reference='1328+307',      #  to the gain calibrator 0917+642. 
               transfer='0917+624');      #  Write solutions to ap366.fluxcal.
calC.plotcal(tablename='ap366.fluxcal',  # Inspect the solutions
             plottype='AMP',
             multiplot=F);

The logger window will report the flux density of the gain calibrator:

  Setting the flux density scale using reference calibrators
  Flux density for 0917+624 (spw=1) is:     1.482 +/-  0.001 Jy
