Mean connectivity of THE THREE HUNDRED groups and clusters at z = 2 as a function of the mass M₂₀₀. The connectivity was estimated at different over-densities: respectively,k₅₀₀ in red, k₂₀₀ in pink, and k_vir in blue. The dashed lines represent the linear fitting. The error bars are the errors on the mean values, computed with the bootstrap method. The mean values have been shifted in mass for visual clarity.
