Dynamical state dependence on connectivity and cluster total mass at redshift z = 0. Panel (a): Degree of relaxation, χ₂₀₀, as a function of the total mass, M₂₀₀. Green, yellow, and light blue dots indicate, respectively, weakly connected (k₂₀₀ < 2), average-connected (k₂₀₀ ∈ {2, 3}), and highly connected (k₂₀₀ > 3) clusters. Panel (b): Degree of relaxation, χ₂₀₀, as a function of the connectivity, k₂₀₀. Green, yellow, and light blue dots indicate, respectively, low-mass (M₂₀₀ < 5 × 10¹³ h⁻¹ M_⊙), medium (5 × 10¹³ ≤ M₂₀₀ h⁻¹ M_⊙ < 5.5 × 10¹⁴), and massive (M₂₀₀ ≥ 5.5 × 10¹⁴ h⁻¹ M_⊙) clusters. The shaded areas and the error bars indicate the error of the mean, computed with the bootstrap method.
