After setting up the analysis_drp repo using setup -j -r analysis_drp, running the following command produces the figure attached to this ticket:

pipetask --long-log run --register-dataset-types \

-b /repo/main \

-i HSC/runs/RC2/w_2021_30/DM-31182 \

--output-run u/lskelvin/coaddQAPlots \

-p $ANALYSIS_DRP_DIR/pipelines/coaddQAPlots.yaml \

-d "skymap='hsc_rings_v1' AND instrument='HSC' AND tract=9615"

(for reference, the pipe_analysis gen2 version of this figure is also attached).

The actual values in the plots seem pretty different--is this because there are still differences in the backgrounds in the Gen2 and Gen3 processing?

Ah yes, thank you for bringing that up. The gen2 plots were scaled into 'human-readable' units by arbitrarily scaling them up by a factor of 10^12 (referenced in the color bar label). The gen3 plots use the more physically motivated nanojanskys, in agreement with DPDD recommendations. Other than that, the two plots above do differ as you suggest also, with the gen2 figure originating from an older build of the stack before a number of changes had been made to data processing (such as switching on Scarlet, for example).

Ok, thanks for the explanation, plus the responses to my questions on the pull request. Looks good to go ahead!

Thanks Clare. Branch merged and deleted!
