Left panels from top to bottom: age distributions from 0.1re to 2re. Analogously, the right panels show the metallicity distributions. The color scheme is the same as in Fig. 6. The rectangles at the top display the average values, and the widths correspond to the respective errors. For our sample galaxies we detect on average a negative metallicity gradient (i.e., higher metallicities in the centers) and a clear negative age gradient (i.e., older stars in the central regions).
