Binary model fit to the 1995 IUE data. Top: flux-weighted mean radial velocities of FeVpsudo and FeVIpsudo (red dots), flux-weighted radial velocities of 1270e (black dots) and Gaussian measured RVs of G1376 (orange dots). The gray and blue curves are the fits to, respectively, the WR star and the less massive object. Middle: flux variations in the 1371e band (red dots) and the calculated flux variation (blue curve) that is obtained from the simultaneous fit to the RVs that are shown in the top panel. Bottom: fit to the 1995 photometric observations of Morel et al. (1997) that were obtained contemporaneously with the IUE-MEGA campaign. The mean of the u and v magnitudes are indicated by green dots. The blue curve indicates the photometric variations that were calculated with the parameters obtained by fitting the IUE data given in the two panels above. The orange shows the results of an independent fit to the photometric observations.
