Radial velocity behaviour of HIP 88745 predicted by the adjustment of the HIPPARCOS and Gaia data. The green dotted line represents the TMB best-fit solution (values in Table 2, solution A) and the black lines show the MCMC solutions. The radial velocity observations from SB9 are in red, the Gaia DR3 radial velocity is in orange, and the ELODIE archive is shown in blue. The systemic velocity of RV₀ = 0.40 km s⁻¹ was determined from an adjustment of the SB9 radial velocities together with TD and Gaia observations, which was performed for the sole purpose of this visualisation.
