De-projected distances between stars with d.o.f. = 4 and star clusters (top panel) or OB associations (bottom panel). On the x-axis, we show the star ID from the sample. The circles show the distance of the closest cluster from each target (method 1), and the squares show the closest cluster with an age similar to that of each star (method 2). The dashed vertical black lines connect the distances from method 1 and method 2 when they find two different stellar groups. The symbols are color-coded according to the derived age of the stars. The horizontal gray lines show the maximum tangential distances that a star can travel in 1 Myr with a constant velocity of 24 km s⁻¹, 100 km s⁻¹, and 200 km s⁻¹. These distances are 24, 102, and 204 pc (horizontal solid, dot-dashed, and dotted lines, respectively). At a distance of 5.3 Mpc, 1 pc is 0.039 arcsec.
