This PR adds a number of new modules used for both shear calibration validation and, in particular, the SuperBIT onboard analysis (OBA).
The new image generation module
imsimwill eventually fully replace our currentgalsimmodule (but is not quite there yet). It has a hierarchical config file instead of a flat one, and does various things that makes it much simpler to run simpler validation tests & full runs using the same code & framework. It will be upgraded iteratively until it reaches the full realism & complexity of the OBA sims.The
obamodule consists of a largely independent, mini-pipeline set of modules that is intended to be run on the SuperBIT onboard sci camera computer QCC. In addition, inoba/simsI've included the code we used to make very realistic image simulations of expected SuperBIT observations to test the OBA on. The interface for these isn't as general as our other options as it prioritized realism & development speed, but we will want to merge the capabilities of both inimsimdown the road.The
CookieCuttermodule is a new "compression" capability for FITS images that takes cutouts of raw images placed at sources detected on fully calibrated images, along with useful meta-data for reconstructing the raw images where we have the data (to eventually be passed to something like MEDS for photometry).While prepping for the OBA, I also created new
coaddanddetectionmodules that can be used independently of the OBA.
