Hi,
I've been starting to play around with pysersic to measure the sizes of compact galaxies, and I have two questions about the parameter, r_eff.
1. Is the best fit value of r_eff the effectiv…

We would like to explicitly compare the timing for photon-shooting vs. DFT branches for various types of profiles. This will be useful for the challenge, but could also be used to give advice for gen…
