Top left: the redshift distribution of the 46 cluster sample based on the photometric redshifts obtained with the red sequence fitting method. Top right: the X-ray temperature distribution estimated from the L − T scaling relation of Pratt et al. (2009). Bottom: distribution of the cluster masses in the r₅₀₀ aperture calculated from the luminosities using the L − M scaling relation from Pratt et al. (2009, see Sect. 3.3.
