Average surface mass density Σ(< R) as a function of radius (from G1) for the best-fit model of MACS J0416.1–2403 for the total mass of the cluster (magenta line), for the cluster members (dashed blue) and for the dark matter halos (dotted red). The black points represents the effective average surface mass density Σ_eff (< R) (for source at redshift z_s = 3) of the cluster and the LOS galaxies, as explained in Sect. 2.1. Of particular interest is the Σ(< R) within ~80^″, which approximately corresponds to the HST FoV at z = 0.396 (~420 kpc).
