Estimated physical torus size as a function of the visibility at 12 μm for the two torus models. Top row: full hydrodynamical torus model (Sect. 3.1); bottom row: clumpy torus model (Sect. 3.2); left panels: Seyfert 1 (i = 0°) case; right panels: Seyfert 2 (i = 90°) case. Different lines in the plots correspond to baseline orientations at different position angles. The maximum range of sizes defined by the interval 0.2 < V < 0.9 is marked by the blue lines and dots. The excluded visibilities are shaded in grey.
