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