Notes. Relations fit to the median age as a function of stellar mass for quiescent and star-forming galaxies using a linear function (Eq. (2)) for the silver and golden LEGA-C samples displayed in the left panels of Fig. 2 and for SDSS DR7 spectra with S/N > 10 (SDSS SN10), shown in the middle and right panels of Fig. 5. The columns list (1) the sample, (2) the intercept P0 at 1011.5 M⊙, and the (3) slope α. The trends for the silver sample are weighted for volume and completeness.
