Fig. 10
Left panel: central age and metallicity versus central velocity dispersion. Right panel: gradients of age and metallicity versus central velocity dispersion. Black and grey squares are early-type galaxies (E/S0, dE/dS0) from Koleva et al. (2011) while red triangles show the investigated FCGs. Error bars for age, metallicity and velocity dispersion were derived from the ULySS fits while gradient errors were computed from the corresponding linear-least squares fits.
