13:26:05 From Troels Christian Petersen : What is the ChiSquare of the fit of star formation? 13:29:41 From Troels Christian Petersen : Same in particle physics… and essentially all other things as well! 13:31:34 From Norman Pedersen : What is the source of all this background noise? 13:33:02 From Troels Christian Petersen : Typically thermal noise - even with cooled apparatus, when pushing the sensitivity (and we have done that!), the thermal noise giving electronic noise is typically the source. But let us ask Gabriel, when there is an opportunity. 13:42:46 From Troels Christian Petersen : Why is the uncertainty on z_phot so large given the very sharp drop-off? 13:48:17 From Norman Pedersen : Is Hubble deep field, Hubble ultra deep field and Hubble ultra deep field IR three seperate telescopes, or one that has been gradually modified ? 13:48:59 From Troels Christian Petersen : All the same - there is only one Hubble… but it has different settings. Again, let us ask Gabriel 13:52:55 From eftsia : Thanks a lot for today Gabe, it has been really informative. It has been very enlightening on a question I have had for a long time 13:53:15 From Marcus Nørgaard Weng : Really nice slides, Gabe! 16:30:23 From Troels Christian Petersen To Gabe Brammer(privately) : Hi Gabriel. Well, you seem to have a good “solution example”, which I will post, if you send it separately. 16:32:06 From eftsia : Ju thanks a lot for today
