(a,b): Positions and proper motion vectors of the young stars. Candidate disk members are shown in red and nondisk members are shown in blue overplotted on an LGSAO image in gray scale. The names of the stars in the primary sample are shown in the left panel and the complete extended sample is shown in a zoomed-out view in the right panel.
(c): Density of normal vectors to the orbital planes of the stars in our primary sample. Densities are indicated in colors (stars/deg^2) and the peak indicates an overdensity of stars with similar orbital planes.
