XGPaint

XGPaint paints maps of extragalactic foregrounds using halo models. We provide CIB and radio models. The CIB model is described in the Websky paper, Stein et al. 2020. The radio model is from Li et al. 2021, a paper in prep for the Websky suite, and is derived from Sehgal et al. 2009.

The general workflow is:

1. Read halos
2. Specify a background cosmology and source model
3. Use the model to put sources in halos
4. Put the sources on maps
