Contours at 95% for different signal-to-noise thresholds, q = 8.5, 7, and 6, applied to the 2015 MMF3 cosmology sample for the SZ+BAO+BBN data set. The contours are compatible with the 2013 constraints (Planck Collaboration XX 2014), shown as the filled, light grey ellipses at 68 and 95% (for the BAO and BBN priors of Sect 5.2; see text). The 2015 catalogue thresholded at q> 8.5 has a similar number of clusters (190) as the 2013 catalogue (189). This comparison is made using the analytical error-function model for completeness and adopts the reference observable-mass scaling relation of the 2013 analysis (1−b = 0.8, see text). The redshift distributions of the best-fit models are shown in Fig. 4. For this figure and Fig. 4, we use the one-dimensional likelihood over the redshift distribution, dN/ dz (Eq. (4)).
