Table 7.

PZPOs for the sample with independent trigonometric parallaxes.

Median	Weighted mean and error	N	Description
(μas)	(μas)
−39	−35 ± 14	57	All that pass the GOF/RUWE selection
−39	−45 ± 14	55	Excluding VY Pyx and vA 645 (10σ outliers)
−45	−71 ± 14	53	Excluding 8σ outliers
−39	−36 ± 14	46	Excluding 6σ outliers
−39	−39 ± 14	39	Excluding 6σ outliers, σ_π < 0.4 mas
−33	−31 ± 16	15	All CCs, T2Cs, RRL that pass the GOF/RUWE selection (and excluding VY Pyx as well)
−33	−29 ± 16	13	As above, excluding Polaris B and FF Aql as well

Notes. Columns 1 and 2 list the median and weighted mean offset between the GEDR3 parallax and the independent trigonometric parallax for the sample discussed in Sects. 3.3 and 5.2. Column 3 lists the number of stars, and Col. 4 gives a description of the selection criteria.
