The initial relative velocity between the two clouds is 10 |$\rm{km\,s}^{-1}$|, but the collisional interaction decelerates the relative velocity to about 7 |$\rm{km\,s}^{-1}$| by 1.6 Myr after the onset of the collision. The present synthetic observations correspond to a relative velocity V0 = 7 |$\rm{km\,s}^{-1}$| at 1.6 Myr. Adapted from Fukui et al. (2018c) with permission.
