Summary of the space motion parameters for the two target stars, given in the heliocentric reference system (H) and corrected for solar motion in the local standard of rest (G).

| G | 6.5 | 55° | 2.6 | 11.8 ± 3.1 | 13° |
Notes. μ and PA give the absolute value and position angle of the proper motion vector, respectively. vr is the radialvelocity of the target. The derived space motion vector is defined by its absolute velocity vs and its inclination with respect to the plane of sky θ (negative values indicate movement towards the observer). The space motion is calculated based on proper motion and vr data from van Leeuwen (2007).
