The mapping from VisBuffer polarizations map to the Image plane polarization.
The latter is determined by the user input, which is passed to the FTMachine in Imager.cc
The map is available in the FTMachine which uses this method to set the map for the CFTerms object.
Reimplemented from casa::refim::CFTerms.

| ) | [inline, virtual] |
Not sure if the following method is requried.
Leaving it in the code for now with an implementation that does nothing.
virtual void applySky(Matrix<Complex>& screen, const Int wPixel, const Vector<Double>& sampling, const Int wConvSize, const Double wScale, const Int inner) {(void)screen; (void)wPixel; (void)sampling; (void)wConvSize; (void)wScale; (void)inner;};
Returns a vector of integers that map each row in the given VisBuffer to an index that is used to pick the appropriate convolution function plane. It also returns the number of unique baselines in the nUnique parameter (unique baselines are defined as the number of baselines each requiring a unique convolution function).
This is required for Heterogeneous antenna arrays (like ALMA) and for all arrays where not all antenna aperture illuminations can be treated as identical.
Implements casa::refim::CFTerms.
