Brightness Profiles of Fiducial Galaxies

Surface brightness profiles of fiducial galaxies along the E, Sph, and dS+I sequences in the core fundamental plane correlations. These galaxies are identified by arrows in the bottom-right panel of the figure on the previous page. Their profiles illustrate very directly (top panel) that Es (identified in the key at upper right) are different from dSphs (identified at lower left) and (bottom panel) that dSphs (filled circles) are similar to dS+Is (open circles) independent of how characteristic parameters are measured.
