\caption{Abundance uncertainties for a $\Delta T_{\rm eff} = 100$ K,
$\Delta$log $g$~= +0.3, $\Delta v_{\rm t} = 0.2$~km~s$^{-1}$ and
corresponding total error. The errors mean the difference in abundance that needs to be
added in order to fit the observed spectrum. The values given are a mean
derived from the  errors  from each line.  }
