I’m working on the agenda for the PSF Session at LSST 2017, and thought it would be a good idea to solicit input from the LSST community, especially since this session wasn’t previously featured on community.lsst.org.
The main items on the agenda so far are:
Updating LSST’s PSF modeling requirements. For this item I’m broadly aware of requirements for weak lensing science, but less so for other kinds of science. If you have PSF model requirements you’d like to discuss, please let me know!
Current thoughts on separately modeling the optics+sensor PSF contribution and atmospheric PSF contribution. I’ll present what I think this might look like and what I think are the most worrisome stumbling blocks and potential research questions.
Chromatic PSF corrections. Meyers&Burchat15 made suggestions for how to implement some such corrections, and I believe Alerts Production has some independent ideas on how to handle differential chromatic refraction for difference imaging. We should compare these.
If you’re working on PSF modeling, and you’d like to contribute to this session, please let me know.
