| 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
| |
