Add an operator that uses bilinear interpolation to generate continuous scanned signal from a HEALPix map. The maps are stored in node shared memory to reduce the required memory.

When scanning and co-adding multiple maps, they may be of different resolutions and some or all interpolated maps may be unpolarized.

You are not using the locally hit sky pixels for anything, so you do not need this trait.
