Notes. Each value is a median or mean of a set of thousands of clones used in a particular simulation with an uncertainty resulting from the obtained distribution. In all cases, perturbations by full Galactic tides are included, while the stellar perturbations are included as follows. For the past motion – BB-prev-A: a swarm of 5001 clones of BB, without stellar perturbation; BB-prev-B: a swarm of 5001 clones of BB, perturbations by all stars included (using nominal orbits); BB-prev-C: nominal orbit of BB and 10 000 clones of star P0230; BB-next-D: 10 000 pairs: comet clone and P0230 clone. For the future motion – BB-next-A: a swarm of 5001 clones of BB, without stellar perturbation; BB-next-B: a swarm of 5001 clones of BB, perturbations by all stars included (using nominal orbits); BB-next-C: nominal orbit of BB and 10 000 clones of star P0107; BB-next-D: 10 000 pairs: comet clone and P0107 clone.
