Stellar Encounters with Beta Pictoris. Table 4

Comparison of encounter parameters with those reported by Kalas et al. (2001). The first and second columns list the Hipparcos source identifiers from Kalas et al. (2001) and the corresponding Gaia DR3 source IDs used in this work. The next columns indicate if the star belongs to a binary or multiple system according to SIMBAD and whether the crossmatch between Hipparcos and Gaia is in agreement with the DPAC recommendations, showing any identification problems. Following Kalas et al. (2001), we computed the 1σ uncertainties for the 2D time-distance distributions. These correspond to the limits of the contour enclosing 39.35% of the most probable data points, based on local density estimates computed from the 1st percentiles of the standardised Euclidean distances, as described in Section 3.1. of Gragera-Más et al. (2025). The final columns list the velocities with their corresponding uncertainties, derived from the 1σ intervals of the marginal distributions, enclosing 68.27% of the most probable values and bounded by the 13.6th and 86.4th percentiles.
