Isosurfaces of the 3D density distributions of the stars shown in Fig. 3. The distribution was smoothed with a Gaussian kernel of radius 2 pc. The lower density level shown is 0.5 stars pc⁻³. Distance from us roughly increases from left to right. The α, δ, and distance arrows correspond to physical dimensions of 20 pc. Components E and J are too sparse to be visible with the adopted contour levels, and component F is behind A and B from this vantage point. The animated figure is available online.
