This is mostly an efficiency PR to speed up random number generation on large arrays. When working on [this imSim PR](https://github.com/LSSTDESC/imSim/pull/284) involving raining lots of photons through a sensor object,...

@jmeyers314 noticed some clear typos in the PhotonDCR `opt_params` class variable, which made it obvious that we don't have any unit tests testing the various ways to make a PhotonDCR...

time DFT vs. photon-shooting branch

10

We would like to explicitly compare the timing for photon-shooting vs. DFT branches for various types of profiles. This will be useful for the challenge, but could also be used...

We should look into WebbPSF to see if this might be a better backend for the WFIRST PSF than what we currently have in the wfirst module. I'm not sure...

PhotonDCR config bugs

1

Placing here so I don't forget: Looks like `PhotonDCR._opt_params` is missing an entry for `obj_coord`. Also, there's a typo: `zenit_coord` -> `zenith_coord`. Need to add some config usage tests.

King density profile implementation

Hello I would like to simulate globular clusters with Galsim. They are usually modelled with a King surface brightness profile. Do you know if this SB is already implemented in...

Hi, I am interested in simulating phase screen with different inner scales. It looks like i can't do that when calling the atmosphere class. Is that something that could be...
