51 // <etymology>
52 // MSPolarization stands for the MeasurementSet Polarization table.
53 // </etymology>
54 //
55 // <synopsis>
56 // An MSPolarization is a table intended to hold the POLARIZATION table for
57 // the MeasurementSet. It has an identical set of member functions as
58 // the main MeasurementSet class, except (currently) for the default
59 // calibration members. For further info and examples see the
60 // MeasurementSet class.
61 // </synopsis>
62 //
63 // <example>
64 // See the MeasurementSet for an example of how to access and use this class.
65 // </example>
66 //
67 // <motivation>
68 // It was found that subtables and the main table of the MeasurementSet have
69 // a lot in common, therefore they derive their interface from the same
70 // base class. Each subtable has its own class to keep the enum definitions
71 // and conversion functions in separate scopes.
72 // </motivation>
73 //
