Notes. The columns represent the Gaia DR2 ID, the time, distance and velocity at the perihelion with its respective confidence interval. These are followed by the effective temperature listed in Gaia DR2, the estimated mass of the star, and the change in the velocity due to the encounter with the Sun for each star.
