\caption{\label{tab5}Abundance uncertainties of HD~10613. The second column gives the variation of the abundance  caused by the variation in $T_{\rm eff}$. The other columns refer, respectively, to the variations due to $\log g$, $\xi$ and $W_\lambda$. The sixth column gives the compounded rms uncertainty of the second to fifth columns. The last column gives the observed abundance dispersion for those elements which abundances were derived using more than three lines.}
