To establish the chemical differences and similarities between the bulge and other stellar populations, we performed an elemental abundance analysis of alpha- (O, Mg, Si, Ca, and Ti) and Z-odd (Na and Al) elements of red giant stars in the bulge as well as of local thin disk, thick disk and halo giants. We use high-resolution optical spectra of 25 bulge giants in Baade's window and 55 comparison giants (4 halo, 29 thin disk and 22 thick disk giants) in the solar neighborhood. All stars have similar stellar parameters but cover a broad range in metallicity (-1.5<[Fe/H]<+0.5). A standard 1D local thermodynamic equilibrium analysis using both Kurucz and MARCS models yielded the abundances of O, Na, Mg, Al, Si, Ca, Ti and Fe. Our homogeneous and differential analysis of the Galactic stellar populations ensured that systematic errors were minimized. Description: Line list and equivalent widths (EWs) of a sample of 80 giant stars in the Galactic bulge, halo, thin- and thick disk. The list includes lines of [OI], NaI, MgI, AlI, SiI, CaI, TiI, FeI and FeII. The adopted oscillator strengths (loggfs) and excitation potential (EP) are also listed. For the bulge stars, the EWs were taken from Fulbrigth et al. (2006, Cat. J/ApJ/636/821, 2007ApJ...661.1152F). Refer to the paper's text for more detail. File Summary:
