[X/Fe] vs. [Fe/H] for the analyzed bulge giants and some previous works. The stars are color-coded as the corresponding fields in Fig. 1, and black diamonds representing the microlensed bulge dwarfs of Bensby et al. (2013), light green squares showing the abundances of Johnson et al. (2014), and golden stars showing the abundances of the high-resolution sample of the GIBS survey (González et al. 2015). 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).
