Λ significance diagram for SDSS clusters of galaxies (purple) with QS superclusters marked in green. The Laniakea supercluster, the central regions of the supercluster A2142 and the Coma cluster with three different mass and size estimates are shown. Inclined lines show the effect of different example mass values. Green vertical lines show the values of the R_ZV (zero velocity radius), R_ZG (zero gravity radius), and the R_ES (the Einstein-Straus radius for the mass 10¹⁴ M_⊙) and the horizontal lines show logarithmic values for the constant ratios of the ⟨ρ_M⟩/ρ_Λ = 6 (ZV), 2 (ZG), and 3/7 (ES).
