Fit of the relation of the observed break radius and the MOND a₀ radius by a law in the form of log₁₀r_br = C₁log₁₀r_a0 + C₀. The black crosses represent the uncertainty intervals of the data. The full red line show the fit and the dotted red lines the fitted intrinsic scatter of the relation. The green dashed line indicates the one-to-one relation. The deviation of the best-fit curve from the one-to-one relation is driven by a few data points.
