Fig. 4


Average light (upper panels) and mass (bottom) fractions due to stars in different age and radial ranges. Each panel corresponds to a bin in the galaxy mass-morphology plane, exactly as in Fig. 3. The three-bar chart histograms in each panel correspond to different galaxy regions: the inner region R ≤ 0.5 HLR (left bar); the whole galaxy R ≤ 2 HLR (central), and outer regions 1.5 <R< 2 HLR (right). Colors represent the following age ranges (in Gyr): < 1 in blue, 1–4 in green, 4–9 in orange, and > 9 in red. Panels in the top right corner show averages for the full sample.
