Mass-weighted age (t_⋆, mw), light-weighted (t_⋆, lw), and Z_⋆ as a function of σ_⋆. The star-forming and quiescent populations are indicated in blue and red respectively, separated based on their UVJ colors. The Spearman’s rank correlation coefficient (ρ) of each galaxy population, is shown at the bottom-left corner of each panel, while the typical error bars are indicated in black at the bottom-right corner. The black lines are the 3^rd order polynomial fits to the median values (black squares) in each 0.1 dex σ_⋆ bin. The associated error bars identify the statistical uncertainties computed as $\sigma /\sqrt{N}$, where N is the number of galaxies within each bin.
