Geometric inclined ring-fit models (ring width =20% of rring,in) of the H- (left) and K-band (right) visibilities. The right plot contains our AMBER data and the KI measurements. The wavelengths are averaged over the whole respective spectral band. The model consists of the unresolved stellar contribution and an inclined ring (see Sect. 3.1). We simultaneously fit all visibilities with a two-dimensional visibility model. The model curves are plotted for all position angles for which visibilities were measured. The color sequence (blue to red) describes the decreasing difference between the PA of the measurement and the disk’s fitted semi-major axis ϑ.
