“…The stellar mass errors contribute 7%, 67%, 36%, 5%, 82%, 95%, 27%, and 84% to the uncertainty of the masses of HD 131664 B, HD 16160 C, HD 161797 Ab, HD 190360 b, HD 190406 B, HD 39587 B, HD 4747 B, and HIP 2552 C, respectively. Second, because the five-parameter astrometry model used in Gaia EDR3 (Lindegren et al 2021) does not account for companion-induced nonlinear motion of a star, the longer baseline of Gaia EDR3 does not improve the fit much for stars with massive companions. In particular, the Gaia EDR3 astrometry is more uncertain than the DR2 astrometry for HD 131664, HD 16160, and HIP 2552.…”
