Top-left: velocity dispersion within a projected radius of R normalized by the velocity dispersion within 1.2 Abell radii as a function of the projected radius. We do not include the values for the clusters having fewer than 10 members within the projected radius we are interested. Top-right: normalized velocity dispersion within a projected radius of r₅₀₀ vs. velocity dispersion. Bottom-left: normalized velocity dispersion within a projected radius of r₅₀₀ vs. offset between the X-ray flux-weighted center and BCG position. Bottom-right: normalized velocity dispersion within a projected radius of r₅₀₀ vs. central cooling time. The results are only based on the observational sample of the 62 clusters. The colors and symbols have the same meaning as those in Fig. 3. The curves are the local regression non-parametric fits.
