Hi all,
I'm trying to use pysersic to fit a sersic profile to synthetic data. I have unitless 2D numpy arrays for the image, mask, and sig files, and I am using a psf generated from WebbPSF for my …

I wanted to know if adding 2 analytic sources or analytic profiles of light from 2 lenses is possible, and if so how to do it. I dont want to switch over to a pixellated model as of now, but do let me…

Hello,
while working on Euclid ERO images I encountered a bug that I don't understand.
I successfully launched model-fitting runs using:
- single-Sersic profile on separate images
- Sersic bulge a…

Hello,
I am running the SLAM pipeline from parametric to pixelization for an interferometer dataset. I modified the script to use the tracer mass of the `mass_total `run of a different dataset for …
