Softening. The Newtonian acceleration field of a star with a mass of 0.5 M⊙ is shown for the case of no softening (ε = 0 pc) and softening with a parameter of ε = 0.001 pc. The dashed horizontal line marks the MONDian acceleration threshold, a0. The vertical solid line indicates the mean central particle distance of ≈0.7 pc for a 400 particle Plummer sphere with Plummer parameter of 3.1 pc.
