Notes. Abundances are given for our best-fit photospheric model Teff/log g/Vtur = 6250/1.5/4.0. Δ[X/H] designates abundance changes corresponding to the changes in Teff/log g of −250 K/−0.5 dex (case A) and + 250 K/+0.5 dex (case B), which are our second best atmospheric model estimates. The flag designates the quality of the N lines used in the averaging, from one for the best cases to three for the worst. Elements with flag 3 had fewer than three lines with EW ≤ 50 mÅ.
