Table 1: Comparison of Lick indices measured on ELODIE stellar spectra with indices from other databases of stellar spectra, for stars in common. The indices for Worthey et al. (1994) were taken from the table published in their paper. The indices for the Jones library were measured by ourselves (see text). The values are the mean offset (ELODIE-other database), the slope of the linear regression and the dispersion $\sigma $ around it (see Fig. 2).
