One-dimensional and two-dimensional posterior distributions of the parameters in the redshift dependent mass bias model, accounting for the in the error bars. Different colours describe the results for the various samples presented in Table 2. For a good visualisation, we only show in grey, green, and red the results for the whole sample, the z < 0.2, and the z > 0.2 ranges, respectively. Dashed distributions have been obtained excluding CL J1226.9+3332 galaxy cluster.
