Spatial distribution of SMC clusters compiled in Bica et al. (2020; gray dots) with the elliptical framework adopted by Piatti et al. (2007) for a semimajor axis of 3° superimposed. The colored age-based vectors represent the residual velocity vectors projected on the sky for the studied cluster sample, namely: the cluster velocity minus the model velocity at its position (left panel), the cluster velocity minus the mean SMC motion (middle panel), and those for the solid lines of Fig. 4 (right panel). The black arrow represents a velocity of 100 km s⁻¹.
