The equivalent widths were measured manually assuming Gaussian profilesor Voigt profiles for the few lines with extended damping wings. Lines with an unsatisfactory fit or significantly affected by telluricfeatures were discarded. Only values eventually retained for theanalysis are provided. For the chemical abundances, the usual notation is used:[X/Y]=[log({epsilon}(X))-log({epsilon}(Y))]star -[log({epsilon}(X))-log({epsilon}(Y))]⊙ with log{epsilon}(X)=12+log[N(X)/N(H)] (N is the number density of thespecies). For lithium, the following notation is used:[Li/H]=log(N(Li))star-log(N(Li))⊙. The adoptedsolar abundances are taken from Grevesse & Sauval(1998SSRv...85..161G), except for Li for which we adopt our derivedvalues: log({epsilon}(Li))⊙=1.09 and 1.13 in LTE and NLTE, respectively (see text).All the abundances are computed under the assumption of LTE, except Li for which values corrected for departures from LTE using the data of Lind et al. (2009A&A...503..541L) are also provided. All the quotederror bars are 1-sigma uncertainties. (6 data files).
