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 [documentation](https://regularizepsf.readthedocs.io/en/latest/index.html).
