Observed a) and modelled b), c) spatial distribution in the Hyades. Blue points are for stars with masses m > 0.5 m⊙, red points for m ≤ 0.5 m⊙. In the modelled distribution, the dynamically unbound particles are marked by black crosses b) or black points c). Two large black circles in a) and b) indicate the distances rc from the cluster centre of 9 pc and 18 pc, whereas in c) the circles correspond to rc = 9 pc, rc = 18 pc, and rc = 30 pc. The last one restricts the area considered in this study.
