that 50 of the de Zeeuw stars have Gaia DR2 parallaxes smaller than 7 mas and/or proper motions outside our selection window. The other six stars did not survive the quality cuts (@2018arXiv180409366L, see also Section \[astdet\]) and, therefore, did not appear in the BS: they are probably too bright ($V<6$ mag) to get accurate parameters in DR2. However, the majority of the de Zeeuw stars in the Crux Cone (85@Hooge00 made use of the ‘Astrographic Catalogue + Tycho’ reference catalogue (ACT) and the Tycho Reference Catalogue (TRC), which are complete to V = 10.5 mag. These catalogues only contain proper motions of a typical accuracy of 3 mas/y, but no parallaxes. So, it is not surprising that among the 1190 Hoogerwerf stars in our area only 289 are in the Crux Cone. About 80@2011MNRAS.416.3108R took the data from the Hipparcos catalogue and combined these with radial velocities taken from the 2nd Catalogue of Radial Velocities with Astrometric Data [@2007AN....328..889K]. Using this data set and a Bayesian membership selection method they found 436 members in the whole Scorpius-Centaurus complex. In CMG we find 76 stars out of their 436, 71 of them are common to @1999AJ....117..354D. Based upon kinematically and
