Diagrams showing positions and motions of sources in the Small Magellanic Cloud. The top left panel shows the positions of the sources that are in the VSS. The bottom left panel shows the distribution of the integrated motion relative to the SMC of B10 sources (that are above the 18 M_⊙ track in Fig. 5) since their birth (see text). The top and bottom right panel show the positions of these B10 sources now and integrated to their their moment of birth in the SMC, respectively.
