Source Model #181

Open Jan-Willem opened 2 weeks ago

Jan-Willem commented 2 weeks ago

The setjy CASA task (https://casadocs.readthedocs.io/en/latest/api/tt/casatasks.imaging.setjy.html) is able to create a virtual model when usescratch=False. We would like to include this model into MSv4, to do this we need the following:

I put an example of MSv2 with virtual model filled for a VLA calibrator, socorro lustre ( /lustre/aoc/users/ttsutsum/xradio/source_model/3C48Ka.ms ). A virtual model as defined in CASA represented by a set of parameters that is used by FTMachine to generate model visibility on the fly. These parameters are mostly specific to FTMachine and so it may not be a good representation of what source model schema should look like. Also, the virtual model does not support ephemeris source model. Setjy creates componentlist that represents a calibrator model so I think I will provide scheme variables based on the componentlist model.
