Top panel: galaxy over densities for systems with distance to filament larger and smaller than 5 R₂₀₀ (red open circles and blue filled circles, respectively). Middle panel: same quantities but for systems with bright (M_r <  −23) and faint (M_r >  −23) central galaxies (green filled diamonds and pink empty diamonds, respectively). Bottom panel: same quantities but for systems with high (L_X >  10⁴³) and faint (L_X <  10⁴³) X-ray luminosities (azure filled squares and violet open squares, respectively).
