REFLEX II cluster density distribution as a function of redshift for the region RA = 150−220° and Dec = −40−0° in the north Galactic cap for the same luminosity limit as in Fig. 8. The density distribution has been corrected by means of the survey selection function and normalised to unity. The region corresponds to region 6dFGS-NGC of Whitbourn & Shanks (2014). We also show the results of their assessment of the galaxy distribution out to z = 0.1 in this region with small red data points.
