Hydra cluster galaxy velocities from 6dFGS (Jones et al. 2009). Blue histogram includes all galaxies within ∼3° (∼2 rvir) of the cluster center. Orange histogram includes galaxies within 40″ of the cluster center. NGC 3311 is the nominal cluster center. NGC 3312, NGC 3314a, and LEDA 753342 appear to belong to substructure at lower systemic velocity along the line of sight. NGC 3314b is substantially redshifted with respect to the cluster center.
