WaveDiff

A differentiable data-driven wavefront-based PSF modelling framework.

WaveDiff is a differentiable PSF modelling pipeline constructed with Tensorflow. It was developed at the CosmoStat lab at CEA Paris-Saclay.

See the documentation for details on how to install and run WaveDiff.

This repository includes:

• A differentiable PSF model entirely built in Tensorflow.
• A numpy-based PSF simulator.
• All the scripts, jobs and notebooks required to reproduce the results in arXiv:2203.04908 and arXiv:2111.12541.
