Cluster density distribution as a function of redshift for the REFLEX II survey in the southern sky (open red circles) and the NORAS II survey in the north (filled blue circles) at |bII| ≥ 20°, for a minimum luminosity of 1042 erg s−1 (0.1–2.4 keV). The density distribution has been normalised by the expected cluster density based on the average luminosity function as explained in Sect. 3.
