The scaling relations of the average occupation number m_k versus kρ^δ at δ = 0.2 for different SF network sizes: (a) L = 1000, (b) L = 2000, (c) L = 4000, (d) L = 8000, at various densities ρ = 0.5 (purple open diamonds), ρ = 2 (blue open triangles), ρ = 10 (red open squares), ρ = 50 (green open circles), respectively.
