Scientific paper

The motivation for this study is to examine the inherent accuracy of the thin-lens approximation typically used in gravitational lensing studies and a new iterative approximation recently introduced 1,2. These two approximations are compared against the numerical integration of the null geodesic equations for an approximate metric describing the lensing scenario. We will refer to this numerical integration as the "exact" method...
