Sky distribution of the clusters (black dots) and their surface density in the CLASSIX survey at |bII| ≥ 20° smoothed with a Gaussian filter with σ = 10° in the redshift slice z = 0 − 0.04 in equatorial coordinates. The colour coding for the density normalised to the mean is orange: > 2, red: 1 − 2, brown: 0.5 − 1, and dark brown/black: < 0.5.
