Notes. Further details on the targets including their co-ordinates can be found in Evans et al. (2006) and Dufton et al. (2019). Targets marked with an asterisk had additional HR02 spectroscopy, whilst luminosities, L, were estimated as discussed in Sect. 2. Radial distances (r) in Col. 5 are in arcmin from #1001 (α = 00 59 04.49, δ = −72 10 24.7, J2000), where 1′≈17.5 pc.
