Distribution of galaxies in the main part of the CB in the plane of the sky. Filled symbols denote galaxies in clusters A2065, A2061, and A2089, and empty circles show other galaxies in the supercluster. Grey crosses denote galaxies in the low-density region with D8 < 5 (partly overlapping with the supercluster region due to projections). Large red circles show the circles with radius of R₃₀ (Table 6).
