Hello,
I'm struggling with the tractor to photometer Galsim-simulated galaxy profiles. I found that the tractor fit typically underestimates given fluxes, and the Gaussian mixture model flux for a …

Based on a discussion with @rmjarvis and @esheldon today, it would be useful to have ways to circumvent the Sersic profile limitation that there is a significant setup time for every single new value …

Right now generating a proposal for a single source (even for the GPU) involves evaluating several bicubic splines and their derivatives using a loop over scipy.SmoothBivariateSpline objects in the CP…

I would like to add a function in the biro solver for the computation of the gradient of the chi squared with respect to Sersic shape parameters. I need it in order to use HMC and I think the best sol…

There should be a single function that provides Sersic parameters instead of a call to each attribute.

When the `setLensPars` method of `FastLensSim` attempts to define a Sersic object, as in [this](https://github.com/tcollett/LensPop/blob/86b40b6470cb458b47ffa2450820b1f923895b6d/FastLensSim.py#L120) l…

In the current code, a component model is created by setting the maximum intensity pixel of the morphology (often central pixel) to 1 and then multiplying the morphology by the spectrum. After PSF con…
