Comparison of the cumulative diameter and mass (luminosities) distribution of models at the present epoch and the SDSS samples. Left panel: cumulative distributions of supercluster geometrical diameters L_g, middle panel: distributions of the fitness diameters L_f, and right panel: total mass (luminosity) distributions ℒ, given in units of the mass (luminosity) of one cell. The SDSS distributions are given for a threshold density D_t = 5.4, and the distribution of SDSS total luminosities is calculated for a correction factor b = 1.45.
