  Neither standard model SEDs nor truncated standard model SEDs fit observed
spectra of QU Carinae with acceptable accuracy over the range 900\AA to
3000\AA. Non-standard model SEDs fit the observation set accurately. The
non-standard accretion disk models have a hot region extending from the white
dwarf to $R=1.36R_{\rm wd}$,a narrow intermediate temperature annulus, and an
isothermal remainder to the tidal cutoff boundary. The models include a range
of $\dot{M}$ values between $1.0{\times}10^{-7}M_{\odot} {\rm yr}^{-1}$ and
$1.0{\times}10^{-6}M_{\odot} {\rm yr}^{-1}$ and limiting values of $M_{\rm wd}$
between $0.6M_{\odot}$ and $1.2M_{\odot}$. A solution with $M_{\rm
wd}=1.2M_{\odot}$ is consistent with an empirical mass-period relation. The set
of models agree on a limited range of possible isothermal region $T_{\rm eff}$
values between 14,000K and 18,000K. The model-to-model residuals are so similar
that it is not possible to choose a best model. The Hipparcos distance, 610 pc,
is representative of the model results. The orbital inclination is between
$40\arcdeg$ and $60\arcdeg$.
