UV diagram showing the distribution of nearby (within 25  pc) late-type stars in UV-space. The Her-Lyr candidates are shown as black circles as in Fig. 9. The data for Her-Lyr is taken from López-Santiago et al. (2006). Downward triangles are Ursa Major (UMa) stars. The ellipses show the 3σ boundary of the displayed clusters as calculated from the space velocities of individual members. UV data are taken from Montes et al. (2001). In addition, the large black pluses show the mean velocities of some moving groups. The location and the ellipse of the Her-Lyr association is calculated from the canonical members.
