Detailed Description

Model the polarization leakage in the Sky Jones Matrices.

Intended use:

Public interface

Prerequisite

SkyEquation class
BeamSkyJones class

Etymology

DBeam = sky-position-dependent polarization leakage, SkyJones = Sky-based Jones matrices. This class only deals with the off-diagonal elements of the primary beam jones matrices.

Synopsis

Example

Motivation

To deal with the polarization leakage beam (mainly Stokes I into polarization visibilities). The main primary beam response, ie, the diagonal Jones matrix elements, are handled by VPSkyJones. The motivation for this split is differing storage requirements for the unerlying PBMath types, and different methods available to VPSkyJones and DBeamSkyJones.

To Do

Waiting for PBMath2D, which requires an HGEOM-like utility. We can do nothing here until this is in place.
Need to check the history that PB has been applied before applying DB (or at least provide for some sort of checking.)
Details of APPLY procedure may need to be modified
