All Tables

Table 1: Observational setup for FLAMES/GIRAFFE ^a.
Table 2: Average abundances obtained at two effective temperature points.
Table 3: Sensitivity of logarithmic abundances to stellar parameters.
Table 4: Stellar parameters and abundances derived for the sample stars. Targets marked with * are the targets of Korn et al. (2007).
Table 5: List of lines used in the abundance analysis, with references to the oscillator strengths used. The columns Waals. , Stark. , and Rad. list the van der Waals, Stark, and radiative damping data (for a description of the data sources, see Barklem et al. 2005, Sect. 3.2, paragraph 5). Rad. is the logarithm (base 10) of the FWHM given in $\rm rad~s^{-1}$ . Non-zero values of Stark. and negative values of Waals. represent the logarithm of FWHM per unit pertuber number density at 10 000 K, given in $\rm rad~s^{-1}cm^{-3}$ . Positive values of the van der Waals parameter correspond to the notation of Anstee & O'Mara (1995), where a packed parameter is used for the broadening cross-section ( $\sigma$ ) for collisions by neutral hydrogen at 10 km s^-1 and its velocity dependence ( $\alpha$ ). E.g. for the Mg I 5172.684 Å line, Waals. =729.238 means $\sigma =729$ in atomic units and $\alpha =0.238$ . d $\lambda _{\rm blue}$ and d $\lambda _{\rm red}$ give the extent of the spectral windows used for fitting of each line, blue-wards and red-wards of the central wavelength. Zero values in both columns indicate that the line-contribution is considered in the same window as the one listed directly above.
