read_processing_set fails using default options #217

Open sstansill opened 1 month ago

I converted a measurement set using the default arguments for convert_msv2_to_processing_set the tried reading it back using read_processing_set and got the following error

The issue In read_processing_set, the variable field_and_source_xds_dict is empty. This happens for both a lofar and VLA dataset that I use for testing. For the VLA dataset, the following warnings were raised by graphviper

WARNING  graphviper:  SOURCE table empty for (unique) source_id [ 0  2 20 21 22 23] and spectral_window_id 3.

For the lofar dataset there was one warning

WARNING  graphviper:  Source_id is -1. No source information will be included in the field_and_source_xds.
