Notes. The spectra signal-to-noise ratios are also indicated, as well as the measured radial velocities. Lithium abundances are derived from the 670.78 nm line for all stars but for #3416, for which the values from both the 670.78 nm and the 610.36 nm lines are reported as (A(Li)670.78 nm/A(Li)610.36 nm).
Abundance derived with 1D-LTE analysis plus NLTE corrections calculated according to Lind et al. (2009). Owing to the grid boundaries, NLTE corrections were adopted assuming ξ = 2.0km s-1.
Radial velocity uncertainty calculated as the difference between the two epochs vhelio multiplied by 0.63 (small sample statistics, see Keeping 1962).
