α∞: α∞, D and E are the three parameters of the MOG model. D: M⊙1/2kpc−1 $\mu=D/\sqrt{M_\star}$ E: M⊙1/2 $\alpha=M_\star\alpha_\infty/(E+\sqrt{M_\star})^2.$ M★: M⊙ Mass that determines α and μ. M: M⊙ The actual gravitating mass. R0: kpc Radius of a (very) naive mass model: e1: $M_{\rm enclosed}=M\exp( 1 - (R_0/r)^{e_1})^{e_2}.$ e2: α: ... the value 1 + α determines the strength of the gravitational constant. μ: ... the inverse of μ determines the range of the repulsive Yukawa-force. r0: ... the range of the Yukawa-force.
