For NOEMA, the UV data can be created from the .IPB, .hpbraw data files using the CLIC script @ all-tables. The resulting UV tables ( .uvt files) should be placed in your working directory.
For ALMA, all relevant Measurement Sets should first be concatenated in a single one. UVFITS files should be created from this concatenated Measurement Set (.ms directory) using the casagildas() Python tool in CASA, and moved tin your working directory. Data for each source/spectral window combination is labelled by SourceName-Frequency where Frequency is the window central frequency in MHz (rounded to nearest integer).
In both cases, 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.
