Hi, I’ve been working on bright stars… the LSST Science book estimates saturation for 15 second exposure in 0.7 arcsec seeing as u, g, r, i, z, y = 14.7, 15.7, 15.8, 15.8, 15.3 and 13.9. Does anyone know if this estimate has changed a lot?
I understand DM will correct for non-linearity as best they can, but how close do you expect to report high quality (say 1% results). I see there was a discussion some years ago that didn’t reach a simple conclusion at:
My goal is simply to understand what stars will have high quality photometry on the LSST system in the case of 15s, 30s exposures, and in the case of additional short exposures.
