I can hear him… but he is breaking up a lot.

Correct me if I’m wrong, but I don’t think anyone has a stable simultaneous multi-object Sersic fitter

I have a question buy my mic not be working: how do you see the interaction between detection and deblending playing out in LSST?
Henry Ferguson

When you do detection on a chisq image are you PSF matching first? How do you deal with the resulting correlated noise?

I haven't thought about all the details, but in theory correlated noise isn't a problem as you can write down the MLE with a covariance matrix. My intuition is that there's a short cut, but I need to do some maths
