The following lists all catalogues of the LOFAR LTA (currently only the MeasurementSet catalogue).
The following lists all tables of the MeasurementSet catalogue. Per table, all columns names are listed, followed by an indicator showing whether this column is relevant for our objective of finding an ontology mapping. For relevant columns, the related IVOA term(s) including their URIs/IRIs are given.
