GLaSS: Generalised Lensing and Shear Spectra
The Generalised Lensing and Shear Spectra (GLaSS) code provides functionality to compute spherical Bessel, tomographic and generalised lensing spectra for weak gravitational lensing (i.e. cosmic shear) studies.
GLaSS provides a module for Cosmosis and is called by Cosmosis. Run-mode options are specified in a Cosmosis ini file. GLaSS can either be run like any other Cosmosis module or interactively in Python. See the jupyter notebooks to see how to run interactively.
