Notes.

^(a)

Observed velocity amplitude;

^(b)

nuclear velocity dispersion (σ_c);

^(c)

mean velocity dispersion (σ);

^(d)

position angle of the major kinematic axis. For the main-NaD and -Hα components, the values in brackets are derived over the same FoV as those for the CO (i.e., within a radius of R ≤ 1.1 kpc).
