Astropy package for source detection and photometry. Maintainers: @larrybradley and @bsipocz
There is no way to get the uncertainty from the Centroids (photutils.centroids) function. I need to be able to retrieve uncertainty due to using the tool to measure velocities requiring...
Since this package has C-extension, might be nice to have a nightly dev wheel uploaded like `astropy`, so downstream packages (e.g., acstools, jdaviz) do not have to build photutils from...
Hi, I wrote a code which uses IntegratedGaussianPRF and PSFPhotometry. Works ok, but the fit is not optimal as my measured stellar profiles are non-Gaussian and are more like Moffat....
I am using the IRAFStarFinder package to detect the stars in my frame but it is missing out even the brightest stars even after setting a very low threshold (image...
I have a SDSS image and I want to subtract the stars from a galaxy  SDSS PSF model is like this: $${\rm PSF} = \exp{\left(-\frac{1}{2}(r/\sigma_1)^2\right)} + b \exp{\left(-\frac{1}{2}(r/\sigma_2)^2\right)} +...
This was an issue that arose when trying to fit a PSF model to data with non-finite values. PSFPhotometry takes in a Fitter obj, however you can't specify `filter_non_finite` when...
I am attempting to run image segmentation on an image from a reasonably large chip and the memory usage is higher than I would have hoped. This script produces the...
I have FITS files of galaxies collected from SDSS. Most of them are not face-on so, I want to to deproject the galaxy to a face-on orientation. I came across...

As [noted in another thread](https://github.com/astropy/photutils/pull/1579#issuecomment-1631151173), I'm consistently getting out-of-memory errors when running the new `PSFPhotometry` fitter. My fitting runs have died at the following stages as ID'd by the progressbar:...
