Panel a) rest-frame velocities of the 44 spectroscopic members of ClG 0332-2747  within 1.0 Mpc from the BCG. Panel b) binned velocity distribution, compared to Gaussians with dispersion obtained through the biweight estimate (red) and considering the jackknife uncertainties (blue and green). All distributions are normalized to 1.0. Panel c) cumulative velocity distributions, colour code as in panel b).
