Detailed Description
A monotone non-negative parameterization \(\tau_c=\tau_{\rm scale}g(\zeta)\) that is approximately the identity away from small values of \(\tau_c\).
More specifically, \(g(\zeta)\rightarrow 0\) as \(\zeta\rightarrow-\infty\) and \(g(\zeta)\approx p\) for large values of \(\zeta\). The transition from a nonlinear to an approximately linear function occurs in the neighbourhood of the parameter \(d_0\).
