Diffusivities are in μm²/ms and T₂ values are in ms.

From enforcing D_||;S, D_||;Z and D_⊥;Z ∈ [0.2 4.0] μm²/ms.

The parameters describing spherical harmonic coefficients, p₂₀, Re(p₂₁), Im(p₂₁), Re(p₂₂), Im(p₂₁), are, for simplicity, represented by the corresponding OD from the Watson distribution (Eq. 21) assuming a main direction of [0 0 1].
