Line-of-sight velocity channel maps in the disk of the MRI model near the burst maximum (top row) vs. those of an idealized Keplerian disk (middle row). The disks are tilted by 30° with respect to the horizontal axis with the upper part being further out from the observer. The color bar presents the deviation from the zero-velocity in km s⁻¹. Each channel shows a velocity interval of 0.4 km s⁻¹. The corresponding gas surface density maps are plotted in pale palette for convenience. The rotation is counterclockwise. Bottom row: deviations in the position angle (δϕ_ch) and velocity (δv_ch) of the center of each velocity channel in the MRI model with respect to the center of the corresponding channel in the Keplerian disk. The centers of the model and Keplerian channels are shown by the blue curves in the top and middle panels for convenience. The values for the upper and lower halves of the disk are shown separately.
