Notes. Solar abundances from Caffau et al. (2011) for Fe and C and from Lodders et al. (2009) for the other elements. For all elements the uncertainty is between 0.15 and 0.2 dex, for iron the quoted error is the σ of the two detected lines. A “:” denotes an uncertain measurement. Li abundances are given as A(Li).
