Caption: Figure 10.

Left: dependence of [Fe/H], [Mg/Fe], and [Mg/H] on the SSP age (first column) and galaxy formation time (second column). Right: dependence of abundances on the galaxy formation time with the stellar mass dependence removed (see Section 5.1). The gray shaded regions show the 68% confidence interval for z ∼ 0 SDSS galaxies. The symbols for galaxies at different redshifts are the same as in Figure 8.
