L_g(observed) vs. L_g(predicted), in units of 10¹⁰h^-2L_⊙. Open circles denote high-luminosity superclusters with the luminosity L_g > 400 × 10¹⁰h^-2L_⊙ and the shape parameter K₁/K₂ > 0.5 (less elongated superclusters), squares denote high-luminosity superclusters with the luminosity L_g > 400 × 10¹⁰h^-2L_⊙ and the shape parameter K₁/K₂ < 0.5 (more elongated superclusters), and grey dots denote superclusters of lower luminosity.
