Hβ (above, top wavelength scale) and Hδ profiles (bottom wavelength scale) for T_eff = 8300 K, log (g) = 3.8 and 9800 K, log (g) = 3.8. Observed profiles are in gray (red in online version) with dots. The fits for the lower temperature are as good or arguably better than at the higher temperature. The relative flux scale is correct for the lowest profile pair. Upper pairs are successively raised by 0.4 units.
