Velocity measurements from FORS2 (blue symbols) and GMOS (green symbols) with respect to the cluster velocity. The shaded grey area indicates the 1-σ confidence level for the cluster mean redshift. The zero point of the radii is defined by the position of the nuclei over which the long slit is placed. Left panel: major axis velocity profile, the red dotted lines indicate the mean velocities North and South of the central galaxy. Right panel: the two intermediate axis velocity profiles. The red crosses in the center mark the positions of the galaxies g3 and “C” that the FORS2 longslit crosses.
