Spectrum synthesis analysis of FUSE and STIS spectra for the cataclysmic variable IX Vel shows that it is possible to achieve a close synthetic spectrum fit with a mass transfer rate of { \dot { M } } = 5 { \times } 10 ^ { -9 } M _ { \odot } / { yr } ^ { -1 } and a modified standard model temperature profile .
The innermost four annuli of the accretion disk model , extending to r / r _ { wd } { \approx } 4 , are isothermal ; beyond that limit the temperatures follow the standard model .

A light synthesis fit to K band photometry requires shallow eclipses of the accretion disk rim and secondary star limb .
The geometry constrains the orbital inclination to i = 57 { \pm } 2 { \arcdeg } .
The synthetic light curve requires a vertically extended accretion disk rim , beyond that predicted by gravitational equilibrium , to shadow the secondary star .
The enhanced vertical extension is consistent with recent MHD predictions for CV accretion disks .

Matching differing observed heights of alternate K band light curve maxima requires a warm rim region downstream of the intersection point of the mass transfer stream with the accretion disk rim .
The temperature of the warm region is inconsistent with expectation for a bright spot associated with a rim shock .
