$\begin{figure} \par\includegraphics[angle=-90,width=8cm,clip]{0678fig1} \end{figure}$ Figure 1: The $q \ {\rm vs.} \ M_1$ plane for P_h = 3 $.\!\!^{\rm h}$ 439 and P_h = 1 $.\!\!^{\rm h}$ 829. The lines of constant inclination refer to K₁=19 km s^-1 (solid) and K₁=29 km s^-1 (dashed), spanning the error range in the value of K₁. The values of i are indicated. The error bars represent the ranges in M₁ and M₂ discussed in the text.

The upper curve is the standard R₁ $\sim$ M₁^-1/3 relation.

$\begin{figure} \par\includegraphics[angle=-90,width=8cm,clip]{0678fig3} \end{figure}$ Figure 3: Comparison between the reddening-corrected SWP spectra of the supersoft source V Sge (continuous line) and of T Pyx (dashed line). The continuum of T Pyx has been scaled to that of V Sge (multiplied by a factor 40). Note the prominence of the high ionization lines of NV $\lambda$ 1240, CIV $\lambda$ 1550, HeII $\lambda$ 1640, and NIV $\lambda$ 1719 in V Sge, in contrast with their moderate intensity or absence in T Pyx.

The three spectra shown here have been re-binned to 20 counts per bin.
