SMODEL
Type: Adverb  (REAL(7))
Use:  This model specifies a point source model to use, usually instead
      of a Clean components model.  A non-zero flux density means this
      model is to be used if  appropriate. The elements of SMODEL are
          SMODEL(1) = flux density (Jy)
          SMODEL(2) = X offset in sky (arcsec)
          SMODEL(3) = Y offset in sky (arcsec)
          SMODEL(4) = Model type:
            0 => point model
            1 => elliptical Gaussian and
                 SMODEL(5) = major axis size (arcsec)
                 SMODEL(6) = minor axis size (arcsec)
                 SMODEL(7) = P. A. of major axis (degrees)
            2 => uniform sphere and
                 SMODEL(5) = radius (arcsec)
            3 => uniform sphere and
                 SMODEL(5) = radius (arcsec)

Null Value:  0
      A null value of SMODEL(1) means no model is specified;
      the useage of null values for other parameters depend on
      the application.
