Webhealpy provides utilities to: convert between sky coordinates and pixel indices in HEALPix nested and ring schemes find pixels within a disk, a polygon or a strip in the sky apply coordinate transformations between Galactic, Ecliptic and Equatorial reference frames apply custom rotations either to vectors or full maps WebI've found a couple of potential solutions, so I'll share incase someone else comes upon this and finds it useful. Solution 1: This sort of depends on the format your data is coming in. Mine came in a (theta, phi) grid.
