Left panel: density contrast Δρ = ρ/ρ_m vs. clustercentric distance D_c for the possible new centre of the main part of the CB. Notations are as in Fig. 13. Arrows mark the distances of clusters A2065, A2061, and A2089 at which they join the possible new collapsing system. Right panel: sky distribution of galaxies in the CB. Filled circles mark turnaround (blue) and future collapse (light blue) zones in the supercluster, as shown in the left panel. Colours are as in Fig. 2.
