Investigate the robustness and performance of fitting the brighter-fatter kernel.
The current approach works, but not always for all sensors and shows amp-to-amp variation. 1. What's the correct way to deal with this?
2. Should the BF kernel itself be averaged across amplifiers and then applied to all?
3. Should the BF kernel be average across sensors and then applied to all (matching) sensors?
4. How should averaging work?
5. Current work has just fit for high-level flats vs. low-level flats and constructed a fixed BF kernel. When should we start fitting the full Photon Transfer Curve?
The current HSC processing uses the BF kernel from just once CCD and applies it to all of them.
The above should be explored in the context of
1. Real data, e.g. HSC, DES.
2. Test-stand data of the LSST sensors.
3. Consider exploring simulated data from DESC DC2
