The target stars plotted in the Stokes q–u plane. The shapes of the markers represent the three distance groupings: Near Group as circles, ζ Oph Group as triangles, and Far Group as squares. The gray line segments (alternating light and dark for visibility) connect the targets in order of increasing distance, beginning with Target 34 and ending with Target 49. For clarity, Target 24 has been offset by −1σ in q and Target 6 has been offset by −0.5σ in q and +0.5σ in u.
