Notes. Linear relations (Eq. (4)) fit to the median stellar age and stellar metallicity as a function of velocity dispersion for quiescent and star-forming galaxies for the silver and golden LEGA-C samples displayed in the left panels of Fig. 4. The columns list (1) the sample, (2) the intercept P0 at 102.4 km/s, and (3) the slope α. The trends for the silver sample are weighted for volume and completeness.
