Description

This would need to take a HDU object since WCS doesn't technically contain the dimensions of the image, only the projection information. I think astropy.wcs.WCS does contain the naxis info, but I've been told that this could be removed at any point since WCS doesn't say anything about the dimensions of the image.

Research direction

No source file or test is identified. Start by examining how FITS HDU objects and astropy.wcs.WCS are handled, especially how image dimensions are obtained; clarify the intended routine interface and expected behavior for every pixel. Done means the routine computes solid angles for all pixels in a FITS image with coverage for the relevant WCS cases.
