Update mask to account for spherical geometry #56

Open kadglass opened 2 years ago

kadglass commented 2 years ago

The mask generation currently does not account for sky curvature, so the mask in the polar region is very patchy. This needs to be adjusted to account for the spherical geometry of the sky (using healpix or something similar).

Hernan reworked the mask to be mapped using healpix - see the VF_HEALPix_mask branch. Its performance needs to be compared with the current version of the code, to make sure that it doesn't slow down the algorithm too much, and then it should be able to be merged in.
