Caption: Figure 9.

Moment 0 for the 12CO J = 3 → 2 eastern nucleus, moment 0 for the 13CO J = 4 → 3 eastern nucleus, and moment 0 for the 13CO J = 4 → 3 western nucleus. Locations where the kinematic profiles were extracted from the data are shown as black crosses. Kinematic profiles were extracted at half-beam increments along the disk’s rotational axis and the perpendicular axis. Sampled locations are spaced by the largest of the half-beam increments of the two sampled axes. Beam sizes are shown in white.
