Notes. The first three columns with values are the input data for the trajectory calculation and the last three are results derived from it at the moment of ejection in the frame of reference of the cluster: the velocity in the plane of the sky vt and the two components of the linear momentum in the plane of the sky. Stellar initial masses are taken from Table A.1 accounting for the masses of Bajamar B, Toronto B, and HD 200 776 B (see Appendix A). The uncertainties in linear momentum do not include uncertainties in the masses but just the ones associated with velocities. The velocities at the time of ejection do not include the deceleration caused by the escape from the stellar system or the cluster and only include the (small) effect of the Galactic potential on the current proper motions.
