get the PBMath object; returns false if that one doesn't exist, true if it does exist and is OK whichAnt is an index into an array of PBMaths, which is different for all telescope/antenna/feed combinations Not sure why we need such a low-level method declared as public, retained to preserve old interface More... | |

Model the diagonal elements of the Voltage Pattern Sky Jones Matrices.
Public interface
VP = Voltage Pattern, SkyJones = Sky-based Jones matrices. This class only deals with the diagonal elements of the voltage pattern jones matrices.
To deal with the non-leakage voltage pattern as applied to all casacore::Stokes, and beam squint (ie, errors in casacore::Stokes V caused by differing RR and LL beams). Polarization leakage beams are in DBeamSkyJones. The motivation for this split is differing storage requirements for the unerlying PBMath types, and different methods available to VPSkyJones and DBeamSkyJones.
