[α/Fe] vs. [Fe/H] for each cell defined in Fig. 20. The number of stars for each cell is indicated next to the panel labels. The rightmost columns, dominated by large eccentricity stars (pressure-supported component), show larger alpha-enhancement ([α/Fe] ∼ 0.25) than what is seen among the low-eccentricity stars. The (inner) thin-disc contribution is seen mostly in the lower row, with a low, near-solar [α/Fe] ratio, which peaks at [Fe/H] = 0.2 in cells (G) and (H), and at 0.25 in cell (I).
