// <etymology>
// BeamSkyJones, derived from SkyJones, describes an interface to
// beam-based SkyJones objects. Like SkyJones, it too is an Abstract
// Base Class, but implements the beam-related methods.

//
// <synopsis>
//
// <motivation>
// The properties of sky-plane based calibration effects must be described
// for the <linkto class="SkyEquation">SkyEquation</linkto>; this class
// encapsulates the antenna beam-based aspects which are present in at least
// a few other specific SkyJones (VPSkyJones and DBeamSkyJones).
// </motivation>
//
// <todo asof="98/11/01">
// <li> Solvable part needs implementation: we need to derive an
// image of gradients of the elements of the Jones matrix. See VisJones
// for how to do this.
// <li> The casacore::MS, version II, will have a beam subtable, which will have PBMaths
// for each antenna. Until this becomes available, we need to do some
// fudging; for example, we
