Fig. 2


Left: reconstructed image of the 2004 epoch using the MIRA software. Three components are resolved (encircled dots) and identified according to their brightness (A, B and C respectively from brightest to dimmest in H). Blue crosses indicate the positions as obtained from model fitting. Centre: presentation of the data from Table 2. Square point represents the alternative position for epoch 2005. Right: predicted H-band flux ratio as a function of the secondary mass with a primary mass of 3.6   M. Shaded region is the flux-ratio constraint from our observations (epoch 2004). Vertical dashed lines provide the system inclination. Vertical blue lines are the secondary mass estimate corresponding to distance d ≈ 414 ± 7 pc.
