## Description

The analysis script was adapted for single visit processing comparisons in DM-4393 and DM-4730. Do the same here for coadd processing comparisons.

Given that DM-6817 shows a bunch of comparisons, I guess a lot of this work has already taken place. Do we have an ETA for completion?

The scripts have been updated for coadd processing analysis (see DM-6817 & DM-6818 for examples of the figures generated). In the context of a single processing run, the following plots are generated, each with a scatter plot of quantity vs. psf Mag with histograms of both axes and the distribution of quantity per source on the sky (to identify any potential spatial variations):

The following use the forced measurements:

 mag_base_CircularApertureFlux_12_0 - mag-base_Psf mag_base_GaussianFlux-psfMagHist - mag-base_Psf mag_ext_photometryKron_KronFlux-psfMagHist - mag-base_Psf mag_modelfit_CModel-psfMagHist - mag-base_Psf 

The following compare the forced and unforced values for a given source:

 compareUnforced_base_CircularApertureFlux_12 - mag-base_Psf compareUnforced_base_GaussianFlux-psfMagHist - mag-base_Psf compareUnforced_ext_photometryKron_KronFlux - mag-base_Psf compareUnforced_modelfit_CModel-psfMagHist - mag-base_Psf 

In the following, "matches" refers to sources matched to a reference catalog (PanSTARRS in this case):

 matches_mag matches_ra matches_dec matches_distance 

In the following, "overlap" refers to matched sources in the patch overlap regions:

 overlap_base_CircularApertureFlux_12_0 overlap_base_GaussianFlux overlap_distance overlap_ext_photometryKron_KronFlux overlap_modelfit_CModel deconvMom pStar

The current version of the script lives in the u/lauren/working branch of the lsst-dm/pipe-analysis repo: https://github.com/lsst-dm/pipe_analysis/tree/u/lauren/working

The work of DM-6816, DM-6817, & DM-6818 has revealed additions and modifications that will help with the QA (identifying the root of the issues of DM-8532 & DM-8533 in particular), so the final clean-up of the script and merging it to the master branch will await those adaptations.
