[X/Fe] for the observed giants in red, compared to abundances of the 604 solar neighborhood dwarf stars of Bensby et al. (2014) with Teff> 5400 K in gray. Especially for O and Ti a clear separation of thin and thick disk-type abundances can be seen in our sample. Since our sample is mostly made up of the very brightest, closest, giants, it is not surprising that a majority of the stars show thin disk-type chemistry. In the plots we use A(O)⊙ = 8.69, A(Mg)⊙ = 7.60, A(Ca)⊙ = 6.34, A(Ti)⊙ = 4.95, and A(Fe)⊙ = 7.50 (Asplund et al. 2009).
