Flux density (S_ν) maps of jet models. Rows show jet models with different inclinations with respect to the observer’s line of sight (i = 1°, 30°, 60°, and 90°, top to bottom). The position angle on the sky of the BH spin axis is PA = 0° for all models. Columns show the maps at different frequencies (22 GHz, 43 GHz, and 86 GHz, left to right). The FOV for each panel is 300 × 300 GM/c² (1600 × 1600 μas). The bottom color bar indicates the flux density in square-root scale, the y axis shows the distance from the BH (located at 0,0) in units of GM/c², and the top x axis that same distance in μas. The green dot represents the position of the intensity weighted centroid.
