Quantitative comparison of the EDGE simulated RAR with our observed dwarf galaxy sample. The black solid line corresponds to the RAR derived by McGaugh et al. (2016) for SPARC local spiral galaxies. The median and 68% scatter in the observed g_obs − g_bar relations are marked by the grey solid lines and shaded regions, respectively. The g_obs − g_bar relations estimated directly from the simulations are represented by solid red lines. The blacked dashed line marks g_obs = g_bar. The small blue points mark the positions of the dSphs on this relation Lelli et al. (2017), while the blue circles indicate the mean and 1σ scatter of the binned data. At the bottom, the residuals relative to the McGaugh et al. (2016) relation (black solid line) are represented for the observed, the simulated, and the Lelli et al. (2017) data.
