Notes. Fe II abundances were adjusted to match the abundances determined from Fe I lines, in order to estimate the surface gravities of the target stars. The difference between the corresponding abundance ratios, [Fe/H]I, and [Fe/H]II, is thus only indicative of the goodness of the gravity estimates.
