PMODEL
Type: Adverb  (REAL(7))
Use:  This adverb specifies a source polarization model of a single
      point source:
                PMODEL(1) = I flux density (Jy)
                PMODEL(2) = Q flux density (Jy)
                PMODEL(3) = U flux density (Jy)
                PMODEL(4) = V flux density (Jy)
                PMODEL(5) = X offset in sky (arcsec)
                PMODEL(6) = Y offset in sky (arcsec)
Null Value:  0
      A null value of PMODEL(1) means no single-component model is
      specified;
Tasks:
   FRCAL.....Faraday rotation self calibration task.
   MAPBM.....Map VLA beam polarization.
   PCAL......Determines instrumental polarization for UV data.
   RLCAL.....Determines instrumental right-left phase versus time (a
             self-cal).
