Top: diameters of clusters versus x-coordinate of the sample L512.2, at threshold densities D_t = 0.832, 3.80, left and right panels, respectively. Bottom: diameters of clusters vs. distance from the observer for the SDSS.2 sample at the same threshold densities. Diameters and distances (x-coordinates) are given in h⁻¹ Mpc; diameters are plotted in a logarithmic scale. Largest percolating clusters are not shown. In all samples a small cluster exclusion limit, N_lim = 500, is applied.
