Comparison of the mean, out-of-eclipse spectrum of ϵ Aurwith some ATLAS synthetic spectra. The best-fitting synthetic spectrum has the parameters: Teff = 8000 K, log g = 1.0 [cgs] log Z/X = –0.3, v(rot) = 5.0 km s-1. Two other synthetic spectra are shown, one with higher gravity and one with lower metallicity.
