* q01 Eri (G=5.38, F9V, Gaia DR3 4912580642524184960) has a wide separation physical companion WT 50 (G=12.56, M4.0Ve, Gaia DR3 4912898156569562624), which shares its Gaia DR3 proper motion and parallax.
The connection between the two and initial separation appear to have been first reported by Fuhrmann & Chini (2018,
2018RNAAS...2...56F
) based on Gaia DR2.
Using Gaia DR3 astrometry, Kervella+ (2022, 2022A&A...657A...7K, J/A+A/657/A7/tablea3) lists separation PA=82.54deg, sep=2151.69" (37400 au). To more significant figures and quantifying the uncertainties using Gaia DR3 (ICRS, epoch 2016.0) astrometry, I estimate: PA = 82.538564 +-0.000002 deg, sep = 2151.686226 +-0.000074 arcsec.
