Required value of A₀ according to the EMOND formalism (Eq. (18)) such that predicted gravitational acceleration from EMOND matches the dynamically calculated acceleration (Eq. (12)) for each cluster in the sample (thin lines). We plotted this required A₀ against the NFW gravitational potential as a estimation of the behaviour within the cluster. The shape takes the form of an exponential function overplotted in red and described by Eq. (19). Also plotted in blue is the more complicated A₀ function described by Eq. (20) with a parameter choice, Φ₀ = −2 700 000² m² s^-2 and A_0max = 80a₀. Note the apparent turnover of A₀ at the deepest potential is an artefact because the total gravitational potential is not just that of an NFW profile as assumed here.
