摘要：

We used the new BaSeL 3.1 spectral library (Westera et al. 2002) along with the latest version of the population synthesis code GISSEL (Bruzual & Charlot 1993) making use of the Padova 2000 tracks (Girardi et al. 2000) to generate theoretical isochrones and spectra. The best fits to the empirical CMD (Rood et al. 1999) were found at [Fe/H] = -1.65 (Z = 0.0004), E(V - I) = 0.00, and (m - M)(V) = 15.27. We derived a most probable age of 12.00 Gyr for the isochrone fit and, for comparison, 12.50 Gyr for the fit to the IUE-spectra.
