| Neutral Shell | northmax | 97 ± 2 (28 ± 2) | |
| southmax | 41 ± 2 (−28 ± 2) | ||
| †Ring 1 | − | 72.9 ± 0.1 (3.9 ± 0.1) | |
| †Ring 2 | − | 76.8 ± 0.1 (7.8 ± 0.1) | |
Notes. The velocities shown are values with respect to Vsys = +69 km s-1. The values in parentheses are given as V − Vsys (velocities corrected for Vsys). Here northmax and southmax refers to the material found furthest out since these type of objects do not have a peak polar region.
Velocities adopted from Castro-Carrizo et al. (2012).
