Deprojected speed-distance pair measurements for different spiral arcs in order to determine the radial dynamics of the wind along the equatorial plane.
| Molecule | Arc | Mean speed | Mean dist. |
|---|---|---|---|
| position | [km s−1] | to AGB [au] | |
| HCN | S | 8.5 ± 3.0 | 41 ± 12 |
| HCN | N | 12.0 ± 3.0 | 90 ± 10 |
| CO | N, last but one | 20.0 ± 6.0 | 570 ± 70 |
| CO | N, farthest | 19.0 ± 5.5 | 1675 ± 140 |
Notes. S stands for south, N for north.
