Profile of RVD for tracers with . The horizontal bars represent the effective radial bin size of the moving average. The vertical bars indicate the spread in the profile due to the inclusion/exclusion of random subsets of tracers. A detailed description of how this profile was obtained is given in Bratek et al. (2014). For comparison, the grey solid circles show the values calculated based on the velocity dispersion points determined in Xue et al. (2008) and Deason et al. (2012b).
