A generalization of the mass-sheet degeneracy producing ring-like artefacts in the lens mass distribution

The inversion of a gravitational lens system is, as is well known, plagued by the so-called mass-sheet degeneracy: one can always rescale the density distribution of the lens and add a constant-density mass sheet such that the, also properly rescaled, source plane is projected on to the same observe...
