Comparison of the observations (left panel; see Fig. 1) with the corresponding model quantities of model 5 for two different PAs of the model image (middle and right panel; the model quantities are calculated for AMBER’s spectral resolution of 12 000, as discussed in Sect. A.3 and Fig. A.3). The middle and right panels show the dependence of the interferometric observables (spectrum, visibilities, wavelength-differential phases, and closure phases) of our best-fit disk-wind model 5 (disk-wind emitting region, continuum accretion disk, plus central star; Tables 3 and A.1) on the wavelength across the Brγ line for an inclination angle of i = 20°, clock-wise motion of the disk wind, and for two different PAs of the projected disk polar axis on the sky: 65° (middle) and 300° (right). Several other PAs that are also approximately in agreement with the observations are discussed in the text and Figs. A.4 and A.5. The detailed dependence of the interferometric observables on the PA is presented in Figs. A.4 and A.5.
