How does CASA calculate the visibility weights?
Posted by Sarah Wood, Last modified by Sarah Wood on 18 February 2020 09:39 PM

A description for how visibility weights are defined and calibrated in CASA is available in this memo and as an appendix in the CASA cookbook from version 4.2.2 onwards.

More information can be found in the Data Weights And Combination CASA Guide.

Note: The treatment of weights depends on which version of CASA is used, as summarized in Table F1 of the above documents.
