    <shortdescription>Insert a source model  a visibility set:</shortdescription>

    <description>

       A source model (souce.model image) or components list is converted into 

       model visibilities that is inserted into the MODEL_DATA column or alternatively 

       is stored  in the header of the MS to be served on the fly when requested.  This is

       needed to use more complicated sources than setjy provides; e.g resolved source 

       or off centered sources in gaincal.  (Setjy will

       automatically make this ft step.)

​

       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 SOC, the models are

       in /usr/lib/casapy/data/nrao/VLA/CalModels.
