Supercluster diameters (left panels) and total weighted luminosities (right panels) vs. distance for fixed and adaptive thresholds. The main sample is shown on the upper row and LRG on the lower. Points mark the diameters and luminosities of individual superclusters; the line is the average with the bin widths of 10 h^-1 Mpc for the main and 25 h^-1 Mpc for the LRG sample. The standard deviations in bins are shown with grey contours.
