Caption: Figure 5.
East–west plots across the nucleus for the panels in Figure 4. Each plot is the median from the central ±4 pixels. The walls of the inner torus produce the double-peak emission. The vertical dashed line is arbitrarily set as a reference to highlight the shift of the intensity profiles from negative to positive velocities.
