\begin{table}%t1 %\centering \par \caption{Comparison of the principal characteristics of publically available libraries of synthetic spectra with resolution better than 5~\AA. {\it N}: number of combinations of atmospheric parameters and rotational velocities. {\it new ODF}: use of the new opacity distribution functions. {\it TiO}: inclusion of the TiO line-list. {\it pred. lines}: inclusion of the "predicted lines''. The last three columns indicate if the spectra are provided for different values of enhancement of $\alpha$-elements, micro-turbulence velocity and rotational velocity.} \includegraphics[width=17.2cm,clip]{2490Tab1.ps} \label{tab1} \end{table}
