Distribution of the low-mass stars from Shkolnik et al. (2012) in the (U, V) plane (left panel) and in the (U, W) one (right panel). We show the locus of both the likely SKG members from our methods and those previously identified by S12. The average velocity components of every SKG (Montes et al. 2001) are indicated with filled circles, while the dash-dotted lines correspond to their 20% threshold in the 3D spatial consideration. In the (U, V) plane, we also over-plotted the loci of the young-disk (YD) and old-disk (OD) populations (Eggen 1973a,b, 1989), which are delimited by the solid line. The position of the Sun is denoted by the corresponding symbol.
