Star cluster mass versus de-projected distance from the SMC center, color-coded according to their de-projected distances from the SMC center. Star clusters with ϵ > 0.4 are highlighted with open black circles. The straight solid line is the relationship found by Joshi et al. (2016) for Milky Way open clusters located within 1.8 kpc of the Sun, while the dashed and dotted lines parallel to that of Joshi et al. (2016) are drawn for comparison purposes (see the text for details).
