Gallery of selected channel maps. Panels show the ¹²CO data channel maps (top row) and best-fit model channel maps (middle row), together with intensity residuals in kelvins for each channel (bottom row). In the bottom row the colorbar has been adjusted such that residuals smaller than 1σ are white. The beam size is depicted in the lower-left corner of each channel. For reference, the best-fit systemic velocity was found to be v_sys = 4.62 km s⁻¹ and the channel spacing is 100 m s⁻¹.
