$\begin{figure} \includegraphics[width=8cm]{3058fig2.ps} \end{figure}$ Figure 2: Best fit of DA models to the Balmer lines H $\alpha$ to H $\delta$ from bottom. The region with the Ca II lines, which also shows H $\epsilon$ in the left wing of the K line and a weak H8, is not included in the fitting, but shown in the figure to preserve the same scale as in the following figures. The profiles have been shifted upwards by 0.4, 0.6, 0.8, 1.7 starting from H $\beta$ .
