The 94 (provisional) cluster members (see also Fig. 3) in the phase space (see top panel). The ordinate is the rest-frame velocity, the abscissa the projected clustercentric distance. Galaxies rejected by the “shifting gapper” procedure are shown with (red) crosses. For the cluster center we adopt the location of the BCG (see text). Big green circles and small points show the differential and integral profiles of the mean velocity (in the middle panel) and the radial velocity dispersion (in the bottom panel). In the bottom panel, two horizontal lines mark the range of possible values for the ICM temperature (7−9 keV) with their respective errors transformed to σ_V (see Sect. 5 for details).
