The rest-frame velocities versus cluster-centric distances of the galaxies with available z. The vertical solid pink line marks the distance to the cluster virial radius, r₂₀₀. Black dots represent the 357 galaxies selected as supercluster members by the algorithm of Mamon et al. (2010), interlopers are marked by X’s. Red circles identify 24 μm emitters. 153 of them are selected as supercluster members.
