From top to bottom: metallicity, [Mg/Fe], and IMF (ξ) scaling relations with galaxy velocity dispersion. The recovered trends agree with expectations from previous studies. In particular, the measured IMF-σ relation is remarkably close to the results of La Barbera et al. (2013) and Spiniello et al. (2014) (gray and orange shaded regions in the bottom panel, respectively), even though they relied on different model assumptions.
