Shear PSF leakage

About

This library quantifies the PSF leakage on weak-lensing galaxy shear
measurements. It computes the following quantities:

  • The object-wise PSF leakage at linear and quadratic order, using regression.
  • The object-wise dependency of galaxy shear to other (scalar) observables.
  • The scale-dependent PSF leakage function galaxy - PSF leakage using
    two-point correlation functions.

Installation

The fastest way to Install this library is with pip automatically from pypi.org,

pip install shear_psf_leakage

Alternatively, you can use TBD
