Notes. The stellar values determined using our analysis for the corresponding star are listed below. In the case of Arcturus (HIP 68673), we have two determinations: the first row shows our results using our FIES-spectrum, and the second row shows our results using the atlas of Hinkle et al. (2000). [Fe/H] is listed in the Asplund et al. (2009) scale, i.e., with A(Fe) = 7.50.
