$\begin{figure} \par\resizebox{8.8cm}{!}{\includegraphics{6758f1.eps}}\end{figure}$ Figure 1: The correlation of the instrumental absorption-line indices obtained with the spectrograph SCORPIO and the standard Lick indices for 22 stars from the list of Worthey et al. (1994). The thin straight lines are bisectrices of the quadrants, and the dashed lines linear regressions fitted to the dependencies. The mean index error for the measurements of the stars by Worthey et al. (1994) are indicated for a single star in each plot; our errors are lower by one order.

The SSP models of Thomas et al. (2003) for [Mg/Fe] = 0.0, +0.3, and +0.5 (the last for NGC 2810 only) are plotted as a reference frame; the solid coloured lines represent stellar population models of equal ages; the metallicities for the models are +0.67, +0.35, 0.0, -0.33 from the top to bottom of each line.

The SSP models of Thomas et al. (2003) for [Mg/Fe] = +0.3 are plotted as a reference frame; thin red and blue lines represent sequences of equal ages and metallicities, correspondingly. At the diagram for NGC 2634 several globular clusters of our Galaxy are also plotted as large red circles.
