Top: column-density channel maps of our hydrodynamical model at an inclination of 15° from the edge-on view of the equatorial plane, and (bottom) the same, but with a pseudo-restriction of the density distributionup to a height of 15 AU. The central velocity of each channel with respect to the systemic velocity (~ − 24.5 km s⁻¹ LSR) is indicated at the top left corner of each panel, and the individual channel width is 4 km s⁻¹. Color bars are in units of g cm⁻² (km s⁻¹)⁻¹.
