Description
for the jax galsim first paper we are interested in investigating the performance of drawing actual galaxy scenes with jax-galsim, not stamps, and compare the performance GalSim both on CPU and GPU.
We are thinking:
- ~ 100x100 pixel images
- use the CATSIM catalog like descwl-shear-sims, use Spergel profiles for Bulges since we don't have DeVacouleurs profile implemented.
- use Moffat profile (need to solve #161 first)
- draw
Sumobject directly rather than adding each object one at a time to the image, do the same in GalSim
