Comparison between the convergence maps for the galaxy cluster MACS J0416, obtained from the B23, EM_spec, and EM_phot strong lensing models. The maps are rescaled such that the ratio of the lens-source and observer-source angular diameter distances equals one. At the top of each column, we show the convergence maps obtained from the different models, while the dots mark the positions of the multiple images. The latter are colour-coded according to their redshifts. The panels at the intersections between pairs of models show the relative difference between the corresponding convergence maps.
