$\begin{figure} \par\includegraphics[width=8.8cm,clip]{1125fig1.eps}\end{figure}$ Figure 1: Nightly FTs of BPM 37093 during ten nights of observations from CTIO in 1996. The amplitudes are highly variable on short timescales. All of the modes vanish below the detection threshold on the final night.

$\begin{figure} \par\includegraphics[angle=270,width=16cm,clip]{1125fig2.eps}\end{figure}$ Figure 2: Fourier Transforms and window functions at the same scale for the Whole Earth Telescope observations of the ZZ Ceti star BPM 37093 obtained during a) the XCOV 16 campaign in 1998, and b) the XCOV 17 campaign in 1999.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{1125fig3.eps}\end{figure}$ Figure 3: The average period spacing of a small grid of models with various combinations of $M_{\rm H}$ and $M_{\rm cr}$ . The 1 $\sigma$ range of the observed average period spacing for BPM 37093 is shown as a shaded area, and the circled point indicates the model with the smallest rms difference between the observed and calculated periods (see text for details).
