Comparison of the cumulative projected total mass profiles of M0416 from this work and that by B21. Top: Cumulative projected total mass profiles of M0416 as a function of the projected distance R from the northern and southern BCG, obtained from our new reference lens model (M_{This work}(BCG-N), M_{This work}(BCG-S)) and from the model by B21 (M_B21(BCG-N), M_B21(BCG-S)). The distances of the observed multiple images from the BCGs used in this work are plotted using small vertical bars. Bottom: Ratio of the same mass profiles as derived from our new reference model and that by B21.
