Notes.

(a)

Ionized species and O are given relative to Fe ii. Abundance ratios are listed relative to iron, save for Fe i and Fe ii (relative to H) and Li.

(b)

Metallicity estimate based on the calcium triplet calibration of Starkenburg et al. (2010).

(c)

Metallicity estimate based on the Mg I calibration of Walker et al. (2007), on the metallicity scale of Carretta & Gratton (1997).
