Age-[Fe/H] and age-[α/Fe] distributions for our subsamples of inner disk stars, as defined by limiting R_guide below 7 kpc. Scatter plots are on the left, while column normalized density plots are on the right. In the scatter plots, the stars are color-coded for their metallicity and [α/Fe] content, while with the black 30% level iso-density contour we show the outer disk stars selected as R_guide greater than 10 kpc.
