Notes. The listed uncertainties give the threshold below which the given percentage of sources can be found in the whole box (or in the SigMA Sco-Cen selection, in parentheses).
Given are the uncertainties for the following parameters: parallax, distance, proper motions in the direction of α and δ, tangential velocities in the direction of α and δ, radial velocities from Gaia DR3, and XYZ. The radial velocities are available for a subsample of 367,127 sources (37%) inside the box (or 4967, 40%, in the SigMA Sco-Cen selection). For the derived parameters we give lower and upper uncertainty thresholds, since the errors, gained via a Monte Carlo approach, get asymmetric for large parallax errors.
