Canopus, Carina and Tucana-Horologium

Following a discussion from Eric Mamajek (see 1st URL below), these figures show the XYZ and UVW positions of Canopus (red sphere with its projections), compared to the Carina and Tucana-Horologium bona fide members (green spheres with their projections) and the spatial / kinematic models of BANYAN II (orange ellipsoid and its projects; see 2nd link below). The age of Canopus is estimated at ~ 27 Myr, which is consistent with both moving groups, however the spatial - kinematic match is not good, at least according to those models.
