−14.98 | 0.05 |
| PRV [d] | 43.1721 | 0.0035 |

| ω [deg] | 21.7 | 0.6 |
Notes.
K1, K2, and V0 are the radial velocity semi-amplitudes and the system velocity; Tperi is the periastron epoch relative to 2016.0, which yields Tperi = BJD 2457373.52; PRV is the period, e the eccentricity, and ω the longitude of the periastron as derived from the fit to the Gaia radial velocity measurements. Gaia DR3 assigns the larger velocity amplitude to stellar component 1. In order to be consistent with the component’s designation, in this Letter component 1 is the more massive star with the smaller velocity amplitude.
