Distribution of groups with at least twelve member galaxies in our superclusters in Cartesian coordinates (see text), in units of h^-1Mpc. To make projection effects less significant we plot in the right panel a slice with y > 140 h^-1Mpc. The filled circles denote groups with at least 50 member galaxies, empty circles denote groups with 30–49 member galaxies and crosses denote groups with 12–29 member galaxies. The numbers are supercluster ID’s (Table 1, Col. 1). Larger ID numbers show superclusters with at least 950 member galaxies, smaller ID numbers – superclusters with less than 950 member galaxies.
