Scientific paper

Oxygen abundances for the 72 program stars. 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. ), and normalized to the new NLTE corrected abundance for the Sun. Column 15 gives the NLTE correction terms from Gratton et al. (1999, Cat. ) (GCEG) that were applied to the abundances in columns 12-14. Column 15 gives the empirical NLTE correction we determined (Eq. 1 in article}. Columns 16-19 give the measured equivalent widths for the forbidden [OI] line at 636.3nm and the permitted oxygen triplet lines at 777nm.
