PNG with DESI Imaging

Attached are machine-readable files for the figures in Rezaie et al https://arxiv.org/pdf/2307.01753.pdf

The predicted density counts in this format: MODEL_lrg_REGION_MAPS.hp256.fits
MODEL is either dnnp (non-linear) or linp (linear)
REGION is either desi (full dr9), desic (desi + dec cuts), desicf (desi + dec + pixel completeness cuts) or desicl (desi + dec + imaging condition cuts)
MAPS is either known (two maps), known1 (three maps), all (eight maps), allp (nine maps), allpext (eleven maps). The paper fiducial analysis uses `dnnp_lrg_desic_allp.hp256.fits`.

The imaging systematic weights are the inverse of the predicted density counts, normalized such that the total number counts of galaxies multiplied by the weight is the same, e.g., Sum_i Ngal_i x Weight_i = Sum_i Ngal_i where Ngal_i is the number of galaxies in pixel i.
