Top panel: CO(3–2) flux-integrated ALMA map from velocity −3 to 11 km s⁻¹ with a robust value of 1. The white contours are 3, 5, 7, 9, 12, 15, 20, 30, and 50 times the rms. Middle panel: ¹³CO flux-integrated ALMA map from velocity −0.08 to 7.44 km s⁻¹. The white contours are 3, 5, 7, 9, and 12 times the rms. Bottom panel: CO(2–1) flux-integrated ALMA map from velocity −2.62 to 10.08 km s⁻¹. The white contours are 3, 5, 7, 9, 12, 15, and 20 times the rms. The beam size is represented by a yellow ellipse in the bottom left corner of the three panels. The three panels show a zoom-in of the main central core region. A zoom-out image can be found in Figs. A.2–A.4 for CO(2–1), CO(3–2), and ¹³CO, respectively.
