Proper Motion of J1207-3900 and J1247-3816 vs TWA Members

This figure shows map of the position and proper motion of bona fide members to TW Hydrae (green arrows; Malo et al. 2013, second link), compared to those of J1247-3816 and J1207-3900 (red arrows; see Gagné et al. 2014b, first link). Each star's proper motion vector is prolongated into a great circle on the celestial sphere, to show that they converge in two points (the apex and anti-apex, blue circles are 1-sigma and 3-sigma apex calculated from the XYZUVW models; See Gagné et al. 2014a; third link), which are often close to the Solar's apex and anti-apex (black cross and plus signs). Thanks to Adric Riedel for help in the construction of these figures, and see some similar figures that he made in the 4th related link.
