[Mg/Fe] vs [Fe/H] plot for stars in Arcturus (as selected by N04 – which intrinsically includes Snoop), Chaka and Herbie from APOGEE in thick grey, turquoise, and magenta dots. We also overlay the original stars used in N04 from the GCCLB dataset. We note that this dataset of metal poor stars was biased and falls at the boundary with the disc as well as the continuation of the chemically thick disc. The larger APOGEE DR14 sample extends just as much into the metal poor end probed by GCCLB and together with the N04 Arcturus sample gives a more complete census on the origin of Arcturus from the chemical side alone. Typical errorbar is marked in red.
