We list again the identifier of each star (1), final stellar parameters (Cols. 2-4), [Fe/H] values (5), and the [X/Fe] ratios (Cols. 6-11). The errors ( $\sigma_1$ , $\sigma_2$ ) are also reported. Average abundances for iron and the other elements are also indicated. ^a] Average values were computed by discarding the coolest star R15; ^b VXR67 and VXR76a were not included in the average; ^c average values by considering only stars with $T_{\rm eff} > 5500$ K.
