Distributions of the normalized parallaxes and proper motion components for the sources in the astrometric selection with 5p (blue) and 6p (green) solutions. The red curves show the corresponding best-fit Gaussian distributions. The global parallax zero point of −0.017 mas of Gaia DR3 is taken into account (Lindegren et al. 2021a,b). The standard deviations of the best-fit Gaussian distributions for the sources with 5p (6p) solutions are 1.048 (1.068), 1.054 (1.092) and 1.063 (1.109) for the parallaxes, and proper motions in right ascension and declination, respectively. As usual in Gaia, the asterisk in α* in the middle panel indicates the implicit factor cos δ, that is .
