3D distribution of galaxies in the CB and in the low-density region around it. Filled symbols denote galaxies in clusters A2065, A2061, A2089, and Gr2064. Empty circles show supercluster galaxies that are not members of these clusters. Grey dots denote galaxies in the low-density region with a global density D8 < 5. Blue circles denote BSF galaxies, orange circles denote RSF galaxies, turquoise green circles mark RQ galaxies, and red circles denote VO galaxies. Green circles mark galaxies in long filaments with a length larger than 5 h⁻¹ Mpc. Large red circles show the circles with a radius R₃₀, which partly overlap because of projections in the 3D view.
