The Kormendy relation. Panel (a): The Kormendy relation of our selected elliptical galaxies (E) in F160W band. The orange dots represent individual elliptical galaxies, and the black solid line is the best linear fitting of these dots. The two black dotted lines show the ±1σ scatter (σ = 0.74). Panel (b): On the Kormendy diagram, the positions of classical bulges (cB: red dots) and pseudo-bulges (pB: blue dots) constrained by both n_b and Kormendy relation are plotted.
