Notes. The table, which is only available at the CDS covers the 117 955 entries of the XHIP catalogue (Sect. 2). These are all Hipparcos-catalogue entries with astrometry. Columns 1–7 refer to data extracted from the XHIP catalogue described in Sect. 2. Cols. 8–10 summarise some key quantities of our method. Columns 11–14 provide data from the N = 10 000 Monte-Carlo simulations that we ran for each star (Sect. 4.4). Columns 15–18 refer to the Gaussian criterion developed in Sect. 5.1. Columns 19–22 refer to the robust criterion, which is described in Sect. 5.2. Columns 2–4: for stars without literature radial velocity, these columns list NaN (see Sect. 2.2); Cols. 8–22: for the 11 171 entries with insignificant parallax measurements in the XHIP catalogue, i.e., 3920 entries with ϖ ≤ 0 and 7251 entries with 0 < ϖ/σϖ ≤ 1, these columns list NaN (see Sect. 4.4); Cols. 16–18: if, for the given value of the confidence level cGauss, the argument of the square root in Eq. (20) is negative, these columns list NaN (see Sect. 5.1); Cols. 16–18 and 20–22: if the radial-velocity precision (standard error) to reach a certain confidence level exceeds 9999.99 km s-1, a value of 9999.99 km s-1 is listed.
