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).
