Geometry and velocity-distance laws.
| Geometry | |

|
|
| Position angle | 60° |
| Inclination | 45° (southwestern is closer) |
| Inner/outer opening angle | 15°/33° |

|
| Velocity law according to Das et al. (2005) | |
| V max@R1 | 800 km s-1 |
| R1/R2 | 96 pc/400 pc |
|
|
|
| Constant velocity law according to Storchi-Bergmann et al. (2010) | |
| VC | 600 km s-1 |
| R | 400 pc |
Notes.Das et al. (2005): Acceleration to Vmax@R1, the maximum radial velocity, occurs at radius R1 and deceleration back to systemic velocity occurs at radius R2. Storchi-Bergmann et al. (2010): constant ejection velocity VC without emission beyond a radial distance of R.
