Galaxy spectral types, as determined from the photometric redshift procedure, vs. TTs for the HNM sample. The symbol style indicates the quality of the de Vaucouleur law fit to the object’s H₁₆₀ surface brightness profile, where a solid square is good, an open square is fair, and a cross is poor. The dashed area in the shape of a square near the bottom shows the area of the primary early‐type sample, and the dotted rectangle encloses the secondary sample of early‐type galaxies, as described in the text.
