Notes. Columns 2, 3, and 4 indicate how the abundances are modified (mean values) when they are computed with over- or underestimated values of Teff(±150 K), log g(±0.3 dex), or Vt(±0.5 dex), respectively. The sum in quadrature of the differences is adopted as the uncertainty in the abundances due to the uncertainties in the atmosphere parameters.
