Star formation history from the AMR and AAR. Top (a): 2D density distribution showing [Fe/H] as a function of stellar age for the full sample. Bottom (b): 2D density distribution showing [α/Fe] as a function of stellar age. A kernel density estimate (KDE) is also overplotted to highlight the density features in the AMR and AAR relationships. The colours represent number of stars per bin in log scale.
