The luminosity of the jet is clearly of stellar origin, and the feature is apparently a planar distribution of stars seen edge-on. Significant differences are apparent in the H-beta profile between spectra of OX 169 obtained in 1983 and 1989: while a relativistic disk model is an excellent fit to the 1989 profile, no such profile can fit the 1983 profile unless azimuthal asymmetries are introduced. These differential variations are used to perform a rough deconvolution of the profile and to show that the broad-line radiation probably arises in two essentially independent regions. A supermassive binary, each component with its own broad-line region, is an attractive model for OX 169.
