Wavelength-dependence of the model visibilities for different baselines for an AGN at 15 Mpc distance and a sublimation radius (=near-IR reverberation radius) of 0.025 pc. Each row represents simulation results of one random arrangement of clouds for different radial power law index a (top: type 1 AGN at i = 0°; bottom: type 2 AGN at i = 90°) with fixed N₀ = 7.5 and R_out = 150. In each panel, we show visibility curves for baseline lengths 45 m (red lines), 60 m (green lines), 90 m (light-blue lines) and 150 m (dark-blue lines). The different lines per wavelength reflect the position-angle dependence of the visibility.
