Scaling relations between age/[M/H] and stellar mass for galaxies with different positions with respect to mean STDMR. Scaling relations with age are shown in the upper panels and the ones with [M/H] are given in the bottom ones. Ages and [M/H] are measured within the inner (r/R_e ≤ 1) and within outer regions (1 < r/R_e ≤ 1.5) of the galaxies (left and right panels, respectively). For individual galaxies, median ages and [M/H] (computed within the corresponding annuli) are plotted as a function of stellar mass color-coded by their vertical offset with respect to the mean STDMR (in the STDMR plane). Median ages and [M/H] of the galaxies above and below the STDMR (see Fig. 3) are indicated with solid lines: red for galaxies above the mean STDMR and blue for the ones below.
