Welcome to the XPIPE weak lensing toolset

xpipe is a python package created to automate work with measuring and calibrating weak lensing shear and mass profiles in wide area lensing surveys such as DES. Features include:

• Automated pipeline for tangential shear and deltasigma profiles

• Object-oriented API for lensing related measurements

• Python wrapper for Erin Sheldon’s xshear.
