Jet front expansion velocity.
| Time period | Apparent speed | Apparent speed | Physical speed | χ2 |
|---|---|---|---|---|
| (μas/day) | (c) | (c) | ||
| 2010–2012 | 0.71 ± 0.03 | 0.29 ± 0.01 | 0.50 ± 0.02 | 1.7 |
| 2013–2016 | 0.549 ± 0.009 | 0.228 ± 0.004 | 0.434 ± 0.007 | 0.81 |
| 2017–2023 | 1.47 ± 0.02 | 0.61 ± 0.01 | 0.69 ± 0.01 | 7.0 |
Notes. We report apparent velocities projected in the image plane and the corresponding physical velocities, assuming an inclination angle of θ = 18°.
