// GJonesDesc defines the format of GJones calibration tables in terms 
// of table descriptors <linkto class="casacore::TableDesc">casacore::TableDesc</linkto>, 
// as used in the casacore::Table system. GJones matrices define the electronic
// gain corrections in the Measurement Equation formalism. At present, 
// this class returns only the default table formats.
