Top: comparison between velocity dispersions calculated from spectroscopic members in this work with those in Rines et al. (2013), and with velocity dispersions calculated by fitting a single isothermal sphere to the weak lensing profile (Hoekstra et al. 2012) for CCCP clusters used in this work. Errorbars are not shown for the latter for clarity. Squares and circles show relaxed and disturbed clusters, respectively. The black line shows the one-to-one relation, and the top axis shows E(z)M200 for a given σ200 from the Evrard et al. (2008) relation. Bottom: distribution of velocity dispersions of the full sample. The gray histogram shows the total distribution, with the blue and red histograms showing the distributions for relaxed and disturbed clusters, respectively.
