Cluster mass profile as obtained from MAMPOSSt (solid blue line) within its 1σ confidence interval (dashed cyan region). The blue dot is the location of [r₂₀₀,M₂₀₀]. The dash-dotted and dashed red lines indicate the cluster mass profile obtained from the Caustic technique and, its 1σ upper and lower limits respectively. The red diamond is the location of [r₂₀₀,M₂₀₀]. The green X symbols indicate the locations of [r₂₀₀,M₂₀₀] obtained using the observed range of cluster T_X and the scaling relation of Vikhlinin et al. (2009).
