imPT

Fast estimator for Lensing Perturbation (imPT) from astronomical images using the auto differentiating function of jax.

A simple code to compute the response to lensing perturbations and remove the bias due to the perturbation from image noise.

Installation

For developers:

git clone https://github.com/mr-superonion/imPT.git
pip install -e . --user

before running code, users need to setup the environment by

source impt_config

Summary

For the first version of imPT, we implement FPFS and use imPT to auto differentiate FPFS.
