Scaling relations between age/[M/H] and total mass for galaxies at different radial annuli, with different positions with respect to the mean STDMR. Scaling relations with age are shown in the upper panels, and the ones with [M/H] in the bottom ones. Ages and [M/H] were 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 total mass and 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 are indicated with solid lines: red for galaxies above the mean STDMR and blue for the ones below it (see Fig. 3). To guide the eye, a halo mass conversion is reported in the upper axis (see text).
