Posterior distributions when the logarithm of the cluster mass is recovered for proj0 of halo-4 at z = 0.22. The black curve shows the reference case, where we model both the mass and the concentration, as in the top panel of Fig. 5. The other histograms show the posteriors when a parametrisation of the concentration-mass relation is assumed; in particular, the orange and olive curves refer to the cases with a constant value of c200 = 3 and c200 = 4, respectively. The vertical dashed black line marks the true value of M200 as computed by AHF.
