We've made an initial pass at this step, and while things mostly worked, we saw a 20% failure rate in the calibrate step in r-band due to using GAIA-DR2 as the reference catalog. It's being discussed extensively on slack as well as in DM-27858.

I think you volunteered for this, Ian Sullivan.

It looks like the "Bright DIA Sources by Collection" plot in the version of the notebook pushed to Github has a bug, and is missing data. The version of that plot you showed at standup included bright DIA sources from each of the collections, and that there was good agreement between the different "flavors" of diffim.

If you're referring to the second bright source plot, that's actually set to only look for collections with "auto" in the name, and in this particular instance there aren't any, since it's just showing the baseline default settings at the moment, best third seeing templates and convolving the template. The one I showed at standup before Thanksgiving was actually a different notebook (same code, just different list of collections) which I currently have as part of DM-36715. I could certainly change things to move them into this notebook if you think the most recent runs fit better in this ticket.

Ian Sullivan I have updated the notebook with the w46 runs shown at the December QA meeting; feel free to take another look.
