Masses of HD 206893 B (left) and C (right) as a function of the on-sky position of HD 206893 C (at the reference epoch of Gaia EDR3, 2016.0) derived from the proper motion anomaly measured between the Gaia EDR3 proper motion and the HIPPARCOSGaia EDR3 long-term proper motion. Physically implausible regions due to negative masses or dynamical instability have been ignored.
