Mass distributions of the clusters of the full Planck cosmological sample, when using the Planck 2015 scaling relation in blue and the relation calibrated in this work in red. The distributions in both panels are obtained from the same sample and identical SZ data. Left: hydrostatic masses i.e. not including a (1 − b) correcting factor, as obtained from Eq. (7). Right: ‘true’ masses, obtained from the full scaling relations including the bias corrections presented in Table 1: $M_{\text{true}}=\frac{M_{\text{hydrostatic}}}{(1-b)}$.
