Intensity cuts for our models. We display cuts along the directions perpendicular to spin (red) and parallel to spin (blue) for spin a = 0.01 for the various thick-disk models used in this article (four central panels), as well as for a spherical model obtained from the thick-disk model in the limit of large disk thickness (top left panel). The size of the critical curve (thin line) and of the primary (n = 0) image of the equatorial horizon (thick line) are shown in green.
