7. Discussion

We have been able to account qualitatively for the phase dependence of the X-ray intensity in the 4.8 hr modulation, using the X-ray emission from the secondary black hole and the emission from the hot post shock gas as well as scattering and attenuation by the post shock gas and the Wolf-Rayet wind. This has been possible by taking the phase 0.0 corresponding to the X-ray minimum to be at the ascending node of the compact object. As mentioned in the introduction there is a controversy as to the configuration of the Wolf-Rayet star and the compact star at the time of the X-ray minimum which needs to be resolved.
