Study of the velocity field of RXCJ1111. Top panel: measured LOS velocity, in the cluster rest frame, of the 104 galaxy members vs projected distance to the centre. The cluster centre is assumed to be the position of the BCG. Middle and bottom panels: integral mean velocity and LOS velocity dispersion, also in the cluster rest frame, shown as radial profiles with respect to the cluster centre. These values are computed by considering all galaxies enclosed in that radius. The first value computed is estimated from the first five galaxies closest to the centre. The error bars are at the 68% c.l.
