Test of our recovery of RAR by applying GRAVSPHERE to mock data drawn from simulated EDGE dwarfs. For this test, we used all of the simulated star particles to fit the photometric light profile and a random 1000 stars to measure the line-of-sight velocity dispersion profile (similar to our more poorly sampled observed dwarfs; see Table 1). The shaded band marks the 68% confidence intervals. The true answer (as determined directly from the simulations, using Equations (1) and (2), assuming spherical symmetry) is marked by the solid lines. The solid black line marks the RAR derived by McGaugh et al. (2016) for SPARC local spiral galaxies. The dashed black line marks g_obs = g_bar.
