$\begin{figure} \par {\includegraphics[width=8cm,clip]{aah3595f3.eps} }\end{figure}$ Figure 3: The H $\alpha$ continuum magnitude of the VW Hyi data as a function of phase. The upper plot has been composed out of data sets 1 ( $\circ$ ), 2 ( $\bigtriangleup$ ), and 3 ( $\Box$ ), with the respective average values subtracted. The lower plot gives those three data sets averaged into bins of 0.05 orbital phases, with the error bars referring to $\pm 1 \sigma$ deviation of the averaging process. The data are repeated to show two orbits.
