A new set of spectral indices computed for the Mg feature at 5175 Å is presented. The spectral indices were computed using the most recent grid of model atmospheres and programs to produce synthetic spectra (Kurucz 1993; CD-Rom 18) for the temperature range 4000-6000 K, and gravity interval log g = 1.5-4.5. The indices reported here refer to solar chemical abundance.
