Posteriors distributions of the recovered mass concentration c_200m and splashback radius R_sp, modelling the black filled circles as in Fig. 1, corresponding the same stacked cluster sample as in Fig. 2. The red solid distribution shows our reference result that is modelling the data up to 12 Mpc/h and adopting Gaussian priors for both the logarithm of the mass and the concentration. The blue-dotted distributions have been obtained modelling the data up to 35 Mpc/h, while the magenta dashed refers to the case in which we assume flat priors for log₁₀(M_200m) and c_200m.
