Upper panel: the same as Fig. 14 – lower panel but for the DS-test with a larger number of neighbors (N_nn = 40). The large faint circle encloses the region within 1.5′from the E peak: galaxies inside define the E1.5 sample. Lower panel: the distribution of δ_s,i deviations in the above DS-test. The solid line represents the observations, the dashed line the distribution for the galaxies of the 1000 simulated clusters, normalized to the observed number.
