Notes. We also present the number of iron lines used for each star to derive the atmospheric parameters. The difference ΔII−I = [Fe ii/ H] − [Fe i/ H] shows the quality in the ionization equilibrium, and the parameters from the linear fitting [Fe i/ H] = aEW ∗ log (EW/λ) + bEW for microturbulence and [Fe i/ H] = aexc ∗ exc.pot + bexc for effective temperature.
