Cluster density distribution as a function of redshift in the northern Galactic cap (filled blue circles) and southern Galactic cap (open red 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.
