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.


In case of questions or if you would like to use parts of this pipeline in a publication, please contact me at
