Log ⟨ ρ_M ⟩ /ρ_Λ vs. log R/ Mpc for example galaxy systems. The inclined lines are for the mass values indicated in M_⊙. Some symbols are slightly shifted in crowded regions. The dotted curve gives the characteristic mass within radius R from the standard 2-point correlation function. “Flat” is the gravity = antigravity line for the limiting case of a flattened system. The region where β^1/2t_Λ/t_cross> 10 is shown.
