GalSim based Rubin Observatory image simulation package
I noticed that the pupil positions of the photon array are being modifed by RubinOptics.applyTo Here "x, y" are references to the pupil values, not copies https://github.com/LSSTDESC/imSim/blob/b6a633f03336f2e0afcd4009558fefb240e118e3/imsim/photon_ops.py#L92 subsequently these get...
For the initial OR3 simulations, there were a lot of concerns regarding the strength of the tree rings appearing in the first round of ComCamSim images, so we reduced tree...
Adds sensor height map data to batoid telescope model. The height data comes from https://ls.st/doc-37242. The more detailed measurements there are fit, for each sensor, to a Zernike model which...
This adds code to calculate centers from shot photons These positions will be accurate in all cases, whereas the current available x, y are from converting ra, dec to x,...
For the ops-rehearsal-3 activities, a number of keywords describing the observations were noted as missing, specifically the `null` ones in this list (see the post in [slack](https://lsstc.slack.com/archives/C064M4D6RC4/p1711141950027439)): ``` RA: 124.82881462031425...
Address #464 take two. I removed the approx_nobject keyword, and now implement getApproxNObjects() by just counting the lines in the instance catalog file. This will always be >= the number...
The current WCS output does not include all the physics, so it is quite far off for some cases, such as when DCR is on. I've got a PR #461...
I'm seeing that instance catalogs are read twice. When galaxies are present its taking about 20minutes to read the catalog, so doubling this is significant. Below I added a timer...
