massmappy

Overview

The massmappy code provides functionality to recover convergence mass maps on the celestial sphere from weak lensing cosmic shear observations. At present the spherical Kaiser-Squires estimator is implemented. Additional estimators will be added in future.

massmappy relies on the SSHT and HEALPix codes to handle sampled data on the sphere.

For further details, please see our related paper: Wallis et al. (2017), Mapping dark matter on the celestial sphere with weak gravitational lensing.
