Ld-Ld pair correlations show that both domain size and alignment increase with ρ. (A) Intraleaflet Ld-Ld pair correlation functions, g(r), plotted from ρ = 0 (green) to ρ = 1 (red). Larger correlations at higher ρ mean domain patches are larger. (B) Interleaflet Ld-Ld pair correlation functions, g1,2(r), plotted from ρ = 0 (green) to ρ = 1 (red). Larger correlations between leaflets at higher ρ mean that domain patches are more aligned between the two leaflets.
