We derived Lick narrow-band indices for 139 candidate super metal-rich stars of different luminosity class for a sample of which fundamental atmosphere parameters have been obtained from a grid of synthetic reference spectra by Malagnini . (2000). Indices include Iron Fe50, Fe52, Fe53, and Magnesium Mgb and Mg2 features. By comparing models and observations, no evidence is found for non-standard Mg vs. Fe relative abundance (i.e. [Mg/Fe] = 0, on the average, for our sample). Both the Worthey . (1994) and Buzzoni . et al. (1992, 1994) fitting functions are found to suitably match the data, and can therefore confidently be extended for population synthesis applications also to super-solar metallicity regimes.
