Parameterization of the kinematics in the CND of NGC 1068 for the ¹²CO( J = 2–1) emission (black filled data points) taken along the slits at different P.A.s (at 0°, 30°, 60°, 90°, 120°, and 150°). σ is the average line-of-sight velocity dispersion, is the rms variation of the velocity from point to point, and Δ is the rotational velocity along each slit (see Section 5.2 for a more detailed description). VNRot = violent non-rotators, CNRot = calm non-rotators, and Rot = rotators. The filled gray data points were determined from the model discussed in Section 5.2.
