Scale-dependent correlation functions of (M_vir, λ), (M_vir, s), and (λ, s), calculated from the MDPL2 Rockstar halo sample with M_vir ≥ 10¹²M_⊙ h⁻¹ (thick solid line). The 1σ error bars around cor(⋅, ⋅|r) = cor(⋅, ⋅) are calculated from 50 halo samples with randomised marks. The exponential, Lorentz, and power-law fits, according to Eq. (8), are shown with thin solid, dashed, and dotted lines, respectively.
