Caption: Figure 3.
Cumulative frequency distribution of the velocity dispersion data shown in Figure 2. The median value (13.3 km s−1) is indicated by the solid gray line. The velocity resolution of the data is 5 km s−1, represented by the gray shaded region. While the majority of the distribution lies below 20 km s−1, there are some regions with dispersions exceeding 50 km s−1.
