The mean V_max–R_max relation of the subhaloes within R₂₀₀ for different host masses across different cosmic web environments. The error bars show the bootstrap errors on the mean. The grey shaded regions at the left of each panel show the subhalo resolution limit of the simulation. Upper panels: Solid lines with error bars represent subhaloes in voids (squares), walls (circles), filaments (diamonds), the cosmic mean sample (triangles), and the equally weighted sample (stars). Middle panels: Fractional deviation of the R_max values of each environment from that of the equally weighted sample, D. Lower panels: Relative divergence of R_max values compared to the full-volume sample, 𝒟. In the ratio panels, the error bars represent the uncertainty obtained via standard error propagation.
