Abstract:
We present the results of the analysis of an extensive set of new and
literature high quality data concerning Fe, C, N, O, Na, and Mg. This
analysis exploited the Teff scale determined in Gratton et al.
(1996, Cat. J/A+A/314/191), and the non-LTE abundance corrections
computed in Gratton et al. (1999, Cat. J/A+A/350/955). Results
obtained with various abundance indices are discussed and compared.
