As discussed in https://github.com/GalSim-developers/GalSim/pull/568#issuecomment-47561275 and subsequent comments, we may want to make a simplified version of the scripts that did the main GalSim validation tests for the GalSim paper, so...
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...
Hi @rmjarvis - Do I understand correctly that the only way to make correlated noise using config is with the `COSMOS` noise option? And that the `file_name`, `cosmos_scale`, and `variance`...
I recently had a reason to make a new version of the 25.2 sample COSMOS catalog with some modifications, and discovered that when I tried to read in and use...
Now that the `galsim.roman` module is up to date with Cycle 7, there are some additional tasks that could be done: - [x] Make Roman module components accessible in config...
As discussed in #923, there are a few issues related to our bandpass definitions: 1. The zeropoints are bandpass zeropoints (mag of object producing 1 count/sec/cm^2 through that bandpass), while...
I've been thinking about the issue of extinction for chromatic objects. For example, for photo-z tests or whatever you might want to be able to draw an image through various...
@gbernstein pointed out that this paper: http://arxiv.org/abs/1406.6072 has an algorithm for making Gaussian random fields that isn't subject to some of the issues that show up with our current periodic...
Today I heard a talk by Gregory Snyder ( @gsnyder206 ) in which he showed something super cool: He's been making synthetic galaxy images from the Illustris simulation to simulate...
For HSC simulations, Francois ( @EiffL ) has been working on a way to easily extrapolate the COSMOS I
