Apparently, there are lab measurements of the brighter-fatter kernel for Roman sensors. We should incorporate that into the galsim.roman model and include it in the standard detector effects.
The ShapeletFitImage function currently still takes a pixel scale parameter for the WCS. It should be updated to take an arbitrary Jacobian matrix to describe the WCS. It's not a...
I've been looking at the new WebbPSF code for rendering WFIRST PSF images [here](https://wfirst.gsfc.nasa.gov/science/WFIRST_Reference_Information.html), and running their script, I got an ImportError from poppy: ``` $ python wim_psf_basic_f0v_even.py Script to...
I've been bitten by this fitsio feature multiple times: When calling `fitsio.write(file_name, data)`, if the file exists already, fitsio will append a new extension rather than overwrite the file. I...
LSST DESC is planning to use SACC files for passing around two-point data. Would be nice to have TreeCorr output to this format natively. cf. https://github.com/LSSTDESC/sacc
In the Y6 testing, we discovered (due to a different bug that was fixed in #136) that the weight adjustment we do to bring nominal S/N values down to the...
Right now our PSF models are all normalized to have unit integral. @erykoff has explained that this isn't the right thing if you expect to get accurate photometry at the...
We should have a shapelet model. This will be another LinearModel class, so I'll hold off doing much work on this until @suchyta1 gets farther along on #5 and that...
GalSim does not have a formal dependency on scipy. For good reason -- that brings in a pretty large dependency tree. (Historically for a better reason, that scipy was notoriously...
