Intensity maps of model RH100 for i = 20° (upper left panel) and i = 160° (lower left panel) at λ = 1.3 mm (ν = 230 GHz). The total fluxes (at 1.3 mm) in these models are 1 Jansky. The position angle of the black hole spin is set to PA = 290° E of N for all models. The image size is 40 × 40 GM_BH/c² in the plane of the black hole, which at a distance of D = 16.7 Mpc, corresponds to an angular size of about 140 × 140 μas. Middle panels: the corresponding visibility amplitude on a u−v plane in units of Jy. Right panels: the visibility phase map in degrees. The arrows in the left and middle panels indicate the orientation of our coordinate system.
