For NOEMA, the UV data can be created from the .IPB, .hpb raw data files using the CLIC script @ all-tables. The resulting UV tables ( .uvt files) should be placed in your working directory.
For ALMA, UVFITS files should be created from the original Measurement Set (.ms directory) using the casagildas() Python tool in CASA, and placed in your working directory.
Once your working directory is loaded with the .uvt or .uvfits files, you can start using the all-widget script, usually through the PIPELINE /WIDGET command.
It is recommended to separate data from different sources into different directory structures, to simplify further processing.
