[Fe/H] versus [α/Fe] for field stars in the three radial regions coloured with the inferred ages using the [Ba/Al] relations computed for each radial region. The dashed black line is the dividing line given by Adibekyan et al. (2012). In the background (grey), we show the field stars excluded from our selection, which are presumably thick-disc and halo stars.
