Abstract

A new photometric system suitable for deep, precise and quick metallicity mapping in galaxies is proposed. We find a linear correlation between our metallicity index and the Mg2 index for stellar, globular cluster, and early-type galaxy spectra, and model spectral energy distributions of the simple stellar populations.

Keywords
