Table 1
Gaia uncertainty scaling factors for the different Gaia data releases (Brown et al. 2012).
| Gaia | ϖ | α∗ | δ | µα∗ | µδ |
|---|---|---|---|---|---|
| DR3 | 1.000 | 0.800 | 0.700 | 1.030 | 0.890 |
| DR4 | 0.749 | 0.800 | 0.700 | 0.580 | 0.500 |
| DR5 | 0.527 | 0.800 | 0.700 | 0.290 | 0.250 |
Notes. Unitless scaling factors for parallax ϖ, right ascension α, declination δ, proper motion in right ascension µα, and proper motion in declination µδ. Uncertainties in the positions and proper motions (in mas and mas/yr) are a function of the uncertainty in parallax (in mas), e.g. σα∗ = 0.800 · σϖ.
