Fig. E.2
Bessel functions of the rings and the star from the best-fit geometric model over data at 1.65 μm. Second-order variations due to the shift of the ring are not taken into account. The outer ring is plotted with a shift corresponding to the fluxes of the inner ring and the star flux ratios. The inner ring is plotted with a shift corresponding to the stellar flux ratio. There are no strong features in the visibilities at the location of the gaps in spatial frequencies. The spatial frequencies are in log scale.
