Left panel: concentration-mass relation of the clusters at z = 0.22. The blue and red data points represent the concentration values computed using the P12 and S08 relations, respectively. The various lines display different concentration-mass relation models computed at z = 0.22. Right panel: ratio of the measured concentration, using different methods compared with respect to the Springel et al. (2008b) formalism. The green crosses and magenta pluses display the case in which we compute the concentration by fitting the differential logarithmic density profile outside 10 and 100 h−1 kpc, respectively.
