Table 6
Parallax corrections for sources with independent parallaxes located at |b| ⩽ 20° with five-parameter solutions.
| Catalogue | ∆ϖ (uncorrected parallax offset) | L21 correction | TW correction | |
|---|---|---|---|---|
| (µas) | (µas) | (µas) | N | |
| VLBI | −8.22 | +21.48 | +9.37 | 32 |
| HST | −22.96 | +1.43 | +1.22 | 7 |
| Red giant | −19.15 | +2.21 | +2.30 | 6300 |
Notes. Column 1 gives the Name of catalogues. Column 2 gives the weighted mean of the offset between the observed GDR3 parallaxes and the independent parallaxes. Column 3 gives the weighted mean of the L21 correction. Column 4 gives the weighted mean of this work. Column 5 gives the number of sources located at |b| ≃ 20° with five-parameter solutions.
