Twin-jet kinematic model for GRS 1758–258 radio jets.
| Parameter | Value |
|---|---|
| Angle of the precession cone |  |
| Inclination of the jet precession |  |
| axis with the LOS | |
| Position angle |  |
| Approaching jet (N) | sjet = +1 |
| Receding jet (S) | sjet = −1 |
| Sense of rotation (clockwise) | srot = −1 |
| Precession period | Pp = (2774 ± 11) d |
| Jet velocity | vjet = (0.330 ± 0.004)c |
| Distance | d = (8.5 ± 0.1) kpc |
