regularizepsf 0.0.3

Point spread function modeling and regularization

regularizepsf

A package for manipulating and correcting variable point spread functions.

Below is an example of correcting model data using the package. An initial image of a simplified starfield (a) is synthetically observed with a slowly varying PSF (b), then regularized with this technique (c). The final image visually matches a direct convolution of the initial image with the target PSF (d). The panels are gamma-corrected to highlight the periphery of the model PSFs.

Getting started

pip install regularizepsf and then follow along with the Quickstart section.
