Comparison of a4/a between the mass and light distributions for our full galaxy sample (black points and histograms) and a subsample with velocity dispersion σv ≥ 200 km s−1 (blue points and histograms). The magenta dashed line means y = x, and the red histogram is the distribution from C. N. Hao et al. (2006a).
