Top: Projected mass M_r in the circular aperture with radius r centred at the northern (red) or the southern BCG (yellow) computed from the best-fit model (solid line) with indicated 68% confidence intervals. The profiles from the best-fit Be23 models are shown in green and blue. The dashed lines represent the cumulative mass M_r contained in the cluster member halos (modelled with the scaling relations). Small vertical bars represent the distances of multiple images from the nothern or southern BCG. Middle: Difference between the total cumulative mass M_r from our model and the Be23 best-fit model relative to our M_r. The confidence intervals are computed from our M_r uncertainty. Bottom: Relative difference between the cumulative mass contained in the cluster member halos from our model and that of Be23.
