Rotation velocity and velocity dispersion of the [C I] (2−1) disk by fitting the approaching side (blue crosses), the receding side (red diamonds), and both sides (green dots). The green band is centered at the median σv = 47 km s−1 from the two-side fitting and has a half-width of 16 km s−1, representing the uncertainty of σv (see Section 4.2).
