Mean effective surface brightness ⟨μ⟩_e versus effective radius R_e for the Sérsic components of E types and the bulges of all Hubble types from S0⁻ to Sm with Inclination ≤ 2, all in the g band (dE types are excluded from this graph). The panels are color-coded by the bulge-to-total ratio B/T_g (left) and the Sérsic index n_g (right) respectively. The black solid line in both panels is the linear fit for EFIGI E Sérsic components, while the dashed lines have the same slope and are offset by ±3 times the rms dispersion in ⟨μ⟩_e around that fit. The departure from the Kormendy relation occurs as both B/T_g and n_g decrease to the lowest possible values, while the highest ones are found for the highest radii along the Kormendy relation.
