Comparison between H I and H II kinematics on small scales. The H I velocity field (top left panel) is a zoomed-in view of the velocity field shown in the top panel Fig. 13. The H II velocity field (top right panel) is the same as in Fig. 12, but regions outside of detected H I have been subdued. In the bottom left panel we show the H II velocity field convolved with a 2D Gaussian (6.1″ × 4.6″, position angle −23.6°) to mimic the VLA B-configuration observations beam smearing (see text). The bottom right panel shows the smoothed Hα velocity field resampled onto the native grid of the VLA B-configuration cube.
