Notes. Error budget for V340 Ara, V500 Sco, and V510 Mon. Columns 7 to 12 list plausible changes in atmospheric parameters: effective temperature (Teff), surface gravity (log g), and microturbulent velocity (vt) together with their impact on Fe I and Fe II abundances. The mean [Fe/H] abundance for each set of intrinsic parameters is also given.
