[α/Fe] (left) and age-[Fe/H] (right) distributions for APOGEE DR17 dwarfs in the form of scatter plots and density distributions. In the top four plots, the ages were determined using Bp-Rp color and Gaia G absolute magnitude, while in the bottom four plots, the ages were determined from Ks magnitudes and Teff effective temperatures. The number of stars in each subsample is indicated inside each density plot (see text for details about the selection of the each subsample).
