We present a progress report on the determination of effective temperature and surface gravity of an extended sample of solar analogs (G0-G3 V), through theoretical line-depth indices (3800<λ<4700Å, FWHM=2.5Å spectral resolution). We applied a set diagnostic diagrams to a selected sample of stars of M67 and found that, under the assumption of solar chemical composition, we obtain a set of atmospheric parameters compatible with those determined from high resolution studies.
