regularizePSF

A Python package for manipulating and correcting various point spread functions.

A Python package for manipulating and correcting variable point spread functions. The package implements a technique for regularizing spatially-varying PSFs in astronomical imaging data. It allows users to correct images observed with slowly varying PSFs and transform them to have a target PSF, improving image quality and enabling more accurate scientific analysis. The technique uses Fourier-domain methods and includes tools for star detection, PSF modeling from stellar cutouts, and visualization utilities.
