Integrated mass profiles obtained with the best-fit parameters of the SIS and NFW density profiles. The values of the projected mass directly measured on the 2D mass map and integrated up to the radii 1 Mpc and 2 Mpc (≃r₂₀₀) are plotted for comparison. They correspond to projected masses inside cylinders so they overestimate the mass by  ~ 25%. The total mass also includes the contribution of A2163-B with a mass of  ~2. The vertical dashed line corresponds to the position of the virial radius r₂₀₀.
