Etymology

Synopsis

This class provides lookup and two level indexing into an MS DataDescription and SpectralWindow subtable. These services include returning list of integer data description IDs (DDID), given a list of Spectral window IDs or frequencies. The DDIDs are then used for selecting rows from the MS (since DDIDs are the primary keys in the maintable - not the spectral window IDs).
