Illustration of the analysis in this work. In color, we show radial profiles of the circular orbit velocity for satellite galaxies similar to Segue 1, Tri II, and Tuc V produced with GALACTICUS. We show the median and 68% scatter at each radius, and different colors correspond to different dark matter (DM) models. For the same galaxies, the points with 1σ error bars mark the observationally inferred circular orbit velocity at the half-light radius.
