Rest-frame velocities vs. distances from the cluster centre for all galaxies with redshifts in the cluster region. Filled (red) dots identify cluster members; the green-crossed red dot is the cD galaxy. The empty circles identify the five interlopers found via the shifting gapper procedure. The empty circles within squares identify the five interlopers found via the adaptive-kernel procedure. Some of these interlopers are nearly coincident in projected phase-space, hence the symbols are superposed.
