NFW halos (Navarro et al. 1997) with different masses within r200. The black filled square is the enclosed mass of Dragonfly 44 within its deprojected half-light radius ﹩{r}_{1/2}﹩. The light open squares are for VCC 1287; the two points are for ﹩{r}_{1/2}﹩ and for the radius that includes all six globular clusters with measured velocities (see Beasley et al. 2016).
