Slices of the full ALMA data cubes, showing the CO J = 3−2 (top) and HCO+ J = 4−3 (bottom) line emission at different velocities, ranging from 9.62 km s⁻¹ to 11.60 km s⁻¹ with a spectral resolution of 0.22 km s⁻¹. Data cubes were rotated 14° counterclockwise to bring the illuminating star direction in the horizontal direction. The synthesized beam size and the kinematic local standard of rest (LSRK) velocities are shown in the bottom left and right corner of each panel, respectively.
