Notes. Numbers in parentheses correspond to the total number of galaxies in each class. Classes correspond to increasing density from 1 to 4. For VMC, classes correspond to 1 + δ < 2, 2 ≤ 1 + δ < 5, 5 ≤ 1 + δ < 10, and 1 + δ ≥ 10. For Voronoi tessellations, the first class contains galaxies for which it was not possible to infer density (field and low richness). For the other density parameters, the first class corresponds to galaxies in the field. Classes 2–4 correspond to Σ < 10 Mpc⁻², 10 Mpc⁻² ≤ Σ < 100 Mpc⁻², and Σ ≥ 100 Mpc⁻² for Voronoi tessellations, 2 ≤ N < 10, 10 ≤ N < 30, and N ≥ 30 for the richness, σ_g < 300 km s⁻¹, 300 km s⁻¹ ≤ σ_g < 500 km s⁻¹, and σ_g ≥ 500 km s⁻¹ for the velocity dispersion, and η ≥ 0.4, 0.1 ≤ η < 0.4, and η < 0.1 for the phase-space parameter. For σ_g and η parameters, galaxies in groups of nine or less members are further discarded.
