Observed (contour) and synthetic (colorscale in units of Jy Beam⁻¹) velocity channel maps of the C¹⁸O emission. The synthetic maps were generated from the kinematical model with V_rel of 0 km s⁻¹ and the asymmetric initial density distribution presented in Fig. 11. Contour levels are from 3σ and increase in steps of a factor of two, where 1σ is 5.5 mJy Beam⁻¹. The central velocity of each channel is labeled at the upper left corner in each panel in units of km s⁻¹. Blue filled ellipses show the size of the synthesized beam.
