Notes. The parameters β and γ are frozen to their “universal” values to break some degeneracy and facilitate the comparison between the results. The first column indicates the subset of our sample chosen to fit the data. We observe that the results on c500 and α of NCC subsample and the result of high redshift subset are compatible within 1σ. The goodness of the fit is indicated in the last column on the right. In general the value of the parameters are very close to the “universal” results of Arnaud et al. (2010), considering that they are highly degenerate. We point out that the parameter P0 for the high redshift bin is significantly smaller than its value for the other bins and the “universal” value.
