Read skyh5 files for source catalogs and diffuse maps #284

Closed rlbyrne closed 1 year ago

rlbyrne commented 2 years ago

Closes #254.

This allows calibration and model catalogs and diffuse Healpix maps to be supplied as pyradiosky-compatible skyh5 files (https://github.com/RadioAstronomySoftwareGroup/pyradiosky) The branch has been tested with both a point source file and a Healpix file, although we may want to do more extensive testing.

Here are results of modeling a Healpix diffuse map provided as a skyh5 file written with pyradiosky. The file is the one provided in the supplementary material of Byrne et al. 2022 (https://academic.oup.com/mnras/article/510/2/2011/6426199). The output images look consistent with the published diffuse map. 1061316296_optimal_Model_I 1061316296_optimal_Model_Q 1061316296_optimal_Model_U 1061316296_optimal_Model_V

I need to check a few things on this, I'm worried that there might be some things that aren't fully general for all skyh5 files. I'll try to figure that out soon!

@bhazelton How would you feel about merging this PR? It's started to clash with other development work.
