GalLenspy: Reconstruction of mass profile in disc-like galaxies from the gravitational lensing effect

Abstract: Gallenspy uses the gravitational lensing effect (GLE) to reconstruct mass profiles in disc-like galaxies. The algorithm inverts the lens equation for gravitational potentials with spherical symmetry, in addition to the estimation in the position of the source, given the positions of the images produced by the lens. Gallenspy also computes critical and caustic curves and the Einstein ring.
