Projected phase-space diagram (line-of-sight velocities vs. cluster-centric distances) of a simulated cluster from the DLB07 sample. Dots (triangles) indicate galaxies selected (respectively, not selected) by CLEAN as cluster members. The red dots represent real members, located within the r₂₀₀ sphere, while green dots represent interlopers, galaxies identified as members but outside the r₂₀₀ sphere. The blue triangles stand for real members (within the r₂₀₀ sphere) incorrectly rejected as interlopers by CLEAN, while black triangles indicate galaxies beyond the 3 Mpc limiting distance of our projected-phase space dynamical analysis.
