Description

I’m currently working with @EiffL on re-implementing the chromatic PSF functionality from the original GalSim in JAX-GalSim.

For now, we are focusing on the case where the SED and morphology are modeled separately. Once this part is in place, we may also extend the implementation to support the other chromatic PSF cases.

Research direction

Start by locating JAX-GalSim’s PSF, SED, and morphology entry points, then compare their behavior with the original GalSim chromatic PSF implementation. Focus first on the separately modeled SED and morphology case; done means that case is reimplemented and covered by the project’s existing tests. The issue names no files or tests, so repository exploration is required.
