Insert a source model into the MODEL_DATA column of a visibility set:
 
 
 
      A source model (souce.model image) or components list is converted into a
 
      model visibility that is inserted into the MODEL_DATA column.  This is
 
      needed to use resolved source in gaincal and in fluxscale.
 
 
 
      Setjy will automatically make this ft step on the
 
      sources currently available are 3C48, 3C138, 3C147, 3C286
 
      at 1.4, 5.0, 8.4, 15, 22, 43 GHz.  Their location is site
 
      dependent.  In Charlottesville and at the AOC, the models are
 
      in /usr/lib(lib64)/casapy/data/nrao/VLA/CalModels.
 
 
 
 
 
      Keyword arguments:
 
      vis -- Name of input visibility file
 
              default: none; example: vis='ngc5921.ms'
 
      field -- Field name list
 
              default: '' ==> all
 
              NOTE: BUT, only one source can be specified in a multi-source vis.
 
              field = '1328+307'  specifies source '1328+307'
 
              field = '4' specified field with index 4
 
      spw -- Spw selection
 
              default: spw = '' (all spw)
 
      model -- Name of input model image
 
              default: '' ==> None;
 
              example: model='/usr/lib/casapy/data/nrao/VLA/CalModels/3C286_X.im'
 
              Note: The model visibilities are scaled from the model frequency
 
                    to the observed frequency of the data.
 
 
 
      complist -- Name of component list
 
              default: None; ; example: complist='test.cl'
 
              component lists are difficult to make.
 
      incremental -- Add model visibility to the existing MODEL_DATA visibilties
 
              default: False; example: incremental=True
