Oxygen abundances in the Galactic disk

Column one gives the Hipparcos number, columns 2-6 the derived oxygen abundances for the different indicators relative to the photospheric oxygen abundance {epsilon}(O)_{sun}_=8.83). Columns 7-11 give the abundances relative to our solar abundances, i.e. [O/H]_{sun}_=0 for all indicators.

Columns 12-14 give the abundances for the triplet that have been corrected for NLTE effects according the the prescription in Gratton et al. (1999, Cat. <J/A+A/350/955>), and normalized to the new NLTE corrected abundance for the Sun. Column 15 gives the NLTE correction terms from Gratton et al. (1999, Cat. <J/A+A/350/955>) (GCEG) that were applied to the abundances in columns 12-14. Column 15 gives the empirical NLTE correction we determined (Eq. 1 in article}.
