  • We extend the model-independent approach to characterise strong gravitational lenses of \cite{bib:Wagner} to its most general form to leading order by using the orientation angles of a set of multiple images with respect to their connection line(s) in addition to the relative distances between the images, their ellipticities and time-delays. For two symmetric images that straddle the critical curve, the orientation angle additionally allows to determine the slope of the critical curve and a… CONTINUE READING
