Effect of the ionized gas disk height on the rotation curve due to the spatial resolution for the Cosmic Snake. The colored solid curves are the rotation curves simulated in the mass distribution corresponding to the parameters listed in Table 2 with an ionized disk height of 1 kpc (orange), 2 kpc (blue) and 3 kpc (pink). The dashed colored curves represent the curves smoothed to the spatial resolution determined by Eq. (2) with their corresponding disk height. The inclination has been fixed to i = 70°, which is the inclination of the Cosmic Snake. The dashed black lines indicate the observed CO and [O II] rotation curves of the Cosmic Snake.
