XYZUVW predicted positions for J1247-3812 and J1207-3900 vs TWA members.

These figures show the expected 3-dimensional XYZ and UVW positions of J1207-3900 and J1247-3812 (see Gagné et al. 2014b, first link below; red points; blue lines point to their projections on the 3 planes), compared to the XYZ positions of bona fide members from Malo et al. 2013 (see third link below; green points; their projections are also shown on the 3 planes, and only vertical lines pointing to their XY-or UV-plane projections are shown for clarity). The orange ellipsoid and its projections on the 3 planes represent the 1.5-sigma contour of the spatial model of the moving group in question. The statistical distance predictions from BANYAN II (see Gagné et al. 2014a, second link below) for RVs and distances were used to compute the XYZ or UVW of the two TWA candidates. Measurements of distance and RVs were used in the case of bona fide members.
