Fast estimator for Lensing Perturbation (impt
) on astronomical images using
the auto differentiating function of jax. The code need to be combined with
estimator (e.g. FPFS) compressing image
to catalog. It is a simple code to infer shear from the catalog with correction for noise bias
For stable (old) version, which have not been updated:
pip install impt
For developers, please clone the repository:
git clone https://github.com/mr-superonion/imPT.git
pip install -e . --user
For the first version of imPT
, we implement FPFS
and use imPT
to auto
differentiate FPFS
.
