Notes. The threshold 30 was set for a probability of false alarm ~ 10-5, assuming that ΔQ follows the χ2 distribution with 5 degrees of freedom. The columns contain the Hipparcos identifier, Hipparcos magnitude, parallax, and total proper motion (all from the Hipparcos Catalogue), the radial velocity from XHIP, and the calculated radial motion and positional offset over Δt = 23.75 yr due to perspective acceleration.
