Caption: Figure 9.

Ideal first moment maps (projected velocity component) for Tempest at various position angles. Only pixels above NHI > 1016 cm−2 are shown for visual clarity. All images are projected at an inclination of 20° at redshift z = 0. The black dashed line shows the direction of the warp, fit by eye. The warp causes what appear to be velocity inversions when it is antialigned with the observed disk major axis (PA = 90°).
