Clumpiness vs. azimuthal scatter computed around R₅₀₀. Top panel: each σ_A refers to a separate map. The color code reflects the 2D classification: VR in blue, R in red, and IR in green. Bottom panel: each cluster is represented only once and the azimuthal scatter is averaged over all its considered projections, ⟨σ_A⟩. The R_3D objects are shown in brown, and the IR_3D clusters in olive green.
