Images of torus model at 0.51 μm for two different luminosities and corresponding inner radii, 10¹¹   L_⊙ and R_in = 0.5 pc (left panel) and 6 × 10¹¹   L_⊙ and R_in = 1.16 pc (right panel). Photocenter in both panels is denoted with a white cross; black hole in both panels is at the center of the images, denoted with “x”. The photocenter offset between the images is 8.4 mas. The values of other torus parameters are the same as in Fig. 5. Images are on a logarithmic scale.
