Caption: Figure 4.

Velocity field (moment-1, color) of the 13C18O J = 2–1 emission overlaid with white contours of the integrated intensity (moment-0), both derived using the bettermoments package (R. Teague & D. Foreman-Mackey 2018). The intensity-weighted velocity was calculated with a 2σ clip to minimize noise bias.
