A toolbox for general elliptical gravitational lenses.
Abstract
We introduce a formalism for constructing models of the gravitational lens action of arbitrary elliptical surface mass distributions including varying ellipticity and isodensity-twist. The projected elliptical surface mass distributions are cut to slices of constant surface mass density for which the deflection is easy to compute. The deflection of the total mass distribution is found by superposition of the action of all slices. numerical - galaxies: elliptical - gravitational lensing - galaxies: clusters of
