This looks great. I just have one comment.
This fixes a nasty bug where MPI calls could get out of sync when using `DeconvolveAnalyticalBeam` in a case where different ranks have differing numbers of frequencies. To rectify this it refactors the code such that the beam_mmodes are generate for all frequencies at once which will prevent the bug from resurfacing in newer implementations.
This allows using a grid beam with a different grid to the underlying data. This can be applied as an external beam when deconvolving ringmaps provided it is higher resolution than the data.
A bug meant that the high-m modes could potentially be left unset as the array was not filled at creation, and the highest modes might not actually be set.
Rename the parameter for consistency
@ssiegelx I think this is done. I added a new |
