AT2021uey alert and baseline object properties from the Gaia DR3 catalogue (Gaia Collaboration 2021).
| Parameters | Values |
|---|---|
| Alert | 2021-07-27 20:51:30 (GMT) |
| (RA, Dec)J2000 | 21:38:10.81, +26:27:59.65 |
| (l, b) | 77∘.91, −19∘.06 |
| Baseline G-magnitude | 15.429 ± 0.003 |
| Parallax (mas) | 0.438 ± 0.047 |
| μ(RA, Dec) (mas/yr) | (−7.912, −5.027) ± (0.045, 0.029) |
| RUWE (*) | 1.478 |
| Distance (kpc) | 2.99 ± 0.08 |
Notes. (*)RUWE: re-normalised unit weight error that indicates the plausibility of parallax estimation. It ideally distributes around 1.0 , and >1.4 is regarded as no signal detection or a problematic astrometric solution (Lindegren et al. 2021).
