Top panel: rest-frame LOS velocity vs. projected clustercentric distance for galaxies of different spectral classes. The cluster center coincides with the position of the BCG and the vertical dashed line indicates the value of R₂₀₀. The horizontal green line indicates the BCG velocity. Middle panel: integral profile of the mean LOS velocity shown through its error bands at the 68% c.l. The mean velocity at a given projected radius from the cluster center is estimated by considering all galaxies within that radius. Small black dots, small red circles, and blue circles show the differential profiles for TOT, PAS, and ELG galaxies (each point is the value computed using 20 galaxies). Bottom panel: as in the middle panel, but for the LOS velocity dispersion (here each point is the value computed using 30 galaxies). The green square indicates the estimate of the X-ray temperature T_X reported by Postman et al. (2012) using Chandra data within the R = 0.714 Mpcradius, indicated by the position of the green arrow, and here converted to σ_V assuming the density-energy equipartition between ICM and galaxies, i.e., β_spec = 1 (see Sect. 5.1).
