3 The spectroscopic data

The reduction and interpretation of the spectra have been explained in detail in Paper I. In the Tables 2 and 3, we give the list of lines used in the abundance analysis, the atomic oscillator strengths (log gf), and measured equivalent widths (in mÅ) for each star. The equivalent widths were measured by interactively fitting single Gaussian functions to the line profiles. The atomic oscillator strengths were taken from Luck & Bond (1985); Thevenin (1989, 1990) and Gurtovenko & Kostik (1989).
