\begin{table}%t5 \par \caption {\label{t5}Sensitivity of derived UVES abundances to the atmospheric parameters and EWs. We reported the error $\sigma_{\rm atm}$ caused by the uncertainties in the atmospheric parameters (${\Delta T_{\rm eff}}$, $\Delta$log~($g$), $\Delta {v_{\rm t}}$, and $\Delta$([A/H])), related to the error in EW measurements ($\sigma_{\rm EW}$), the squared sum of the two ($\sigma_{\rm tot}$), and the observed dispersion ($\sigma_{\rm obs}$) for each element.} %\centering \par \begin{tabular}{ l r r r c c c c c c} \hline\hline \ & $\rm {\Delta T_{\rm eff}}$ [K] & $\Delta$log~($g$) & $\Delta \rm {v_{t}}$ [km $\rm {s^{-1}}$] & \ $\Delta$([A/H]) [dex]&$\sigma_{\rm {atm}}$ & $\sigma_{\rm {EW}}$ & $\sigma_{\rm {tot}}$ & $\sigma_{\rm {obs}}$\\ \hline &$+50$ &$+0.14$ &$+0.13$ &$+0.10$ & & & & \\\hline ${\rm [O/Fe]}$ &-- &-- &-- &-- & -- & -- & 0.04 & 0.20 \\ ${\rm [Na/Fe]}$ & $-$0.02 &$-$0.01 &$+$0.01 &$-$0.01 & 0.03 & 0.01 & 0.03 & 0.30 \\ ${\rm [Mg/Fe]}$ & $-$0.03 &$+$0.00 &$+$0.01 &$-$0.01 & 0.03 & 0.02 & 0.04 & 0.11 \\ ${\rm [Al/Fe]}$ & $-$0.03 &$-$0.01 &$+$0.02 &$-$0.01 & 0.04 & 0.06 & 0.07 & 0.31 \\ ${\rm [Si/Fe]}$ & $-$0.05 &$+$0.01 &$+$0.01 &$+$0.01 & 0.05 & 0.01 & 0.05 & 0.03 \\ ${\rm [Ca/Fe]}$ & $-$0.01 &$-$0.01 &$-$0.01 &$-$0.01 & 0.02 & 0.01 & 0.02 & 0.07 \\ ${\rm [Sc/Fe]}$ & $+$0.03 &$+$0.00 &$+$0.00 &$+$0.00 & 0.03 & 0.03 & 0.04 & 0.04 \\ ${\rm [Ti/Fe]_{TiI}}$ & $+$0.04 &$-$0.01 &$+$0.00 &$-$0.02 & 0.05 & 0.01 & 0.05 & 0.06 \\ ${\rm [Ti/Fe]_{TiII}}$& $+$0.02 &$-$0.01 &$-$0.02 &$-$0.01 & 0.03 & 0.02 & 0.04 & 0.06 \\ ${\rm [V/Fe]}$ & $+$0.03 &$+$0.00 &$+$0.03 &$-$0.01 & 0.04 & 0.01 & 0.04 & 0.10 \\ ${\rm [Cr/Fe]}$ & $+$0.02 &$-$0.03 &$-$0.01 &$-$0.02 & 0.04 & 0.01 & 0.04 & 0.08 \\ ${\rm [Fe/H]_{FeI}}$ & $+$0.07 &$+$0.00 &$-$0.02 &$-$0.01 & 0.07 & 0.06 & 0.09 & 0.10 \\ ${\rm [Fe/H]_{FeII}}$ & $-$0.02 &$+$0.05 &$-$0.02 &$+$0.02 & 0.06 & 0.06 & 0.08 & 0.10 \\ ${\rm [Ni/Fe]}$ & $-$0.01 &$+$0.00 &$+$0.01 &$+$0.00 & 0.01 & 0.01 & 0.01 & 0.04 \\ ${\rm [Y/Fe]}$ & $+$0.03 &$-$0.01 &$-$0.02 &$+$0.00 & 0.04 & 0.01 & 0.04 & 0.27 \\ ${\rm [Zr/Fe]}$ & $+$0.03 &$+$0.00 &$+$0.02 &$+$0.00 & 0.04 & 0.01 & 0.04 & 0.23 \\ ${\rm [Ba/Fe]}$ & $+$0.05 &$-$0.01 &$-$0.09 &$+$0.00 & 0.10 & 0.03 & 0.10 & 0.23 \\ \hline \end{tabular} \end{table}
