massmappy 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 also supports numerous projection operator to project the sphere to planar regions for comparison with the spherical Kaiser-Squires estimator.
massmappy relies on the SSHT (built on the MW sampling theorem) and HEALPIX codes to handle sampled data on the sphere.
