Position-velocity slices through the data cubes along the major axis of rotation. The left column shows the integrated flux map of the HCN 3–2 transition, with the location of the 07 by 0033 PV slice through the data cube containing the HCN 3–2 transition. The contours show 3, 6, 12, 24, and 48 times 0.3 mJy. The horizontal dashed black lines show the systemic velocity of the indicated transitions, and the velocity axis is shown in the optical convention utilizing the rest frequency of the HCN 3–2 transition.
