Two-dimensional projected mass as a function of the radius measured from the BGG. The green and blue shaded areas corresponds to the mass profile within 1σ errors for the SL+Dyn model and the weak lensing model reported in VMM11, respectively. The orange-shaded region shows the area where the arc systems lie. The two red triangles with error bars show two estimates (at 0.5 and 1 Mpc) of the weak lensing mass from Foëx et al. (2013). Black diamonds (shifted in r-0.05 for clarity) show the predicted mass calculated from the work of Lieu et al. (2016). Cyan diamonds (shifted in r+0.05 for clarity) are the masses calculated from Lieu et al. (2016) data, but assuming c₂₀₀ = 10 (see text). We also depict with two arrows, our best r_s (for c₂₀₀ = 10), and the r_s (for c₂₀₀ = 2.7) reported in Lieu et al. (2016).
