Image Details
Caption: Figure 19.
Left panels: as Figure 18, but with galaxies color coded according to morphology: quiescent early-type galaxies (i.e., E-Q morphology); early-type galaxies with some level of star formation (E-I and E-A as well as early-type to irregular or spiral transition objects (EI and ES); and all spiral (S), irregular (I) or transition (SI) galaxies (see Section 5.5). See the text for further details. Right panels: as the left panels, but showing LOWESS fits and associated 95% confidence limits to the data. The fits are performed using the entire sample and separately for galaxies of different morphologies, as shown in the legend. Data points are shown as gray dots; note, however, that to better show the fits, the y-axis has been expanded compared to the let panels and some points fall outside the range plotted.
