• Say 1257 files here and do binned stats. Get data, model and you see the rings. This is probably due to thickness, and we are thinking of incorporating in the PSF model. If single number, wrong at ±2%. In alert pipeline, looking at residual vs PS, see the same map. Not from PSF, but simply from photo.

Closing Remarks:

• Jakob: upgrading UH88 (?) Might use some of that time if we have candidate 1a that are too faint.
