Rotation curves obtained in the simulated mass distribution corresponding to the parameters listed in Table 2, with two tracers: the molecular and ionized components. The results from the simulation for the molecular and ionized gas disks are shown in orange and in blue, respectively. The upper and lower boundaries of the ionized gas disk (taking the absolute values) represent a height of 1 kpc and 3 kpc, respectively. The dashed black lines indicate the observed CO and [O II] rotation curves of the Cosmic Snake.
