CombGaussLorentzKT

Description

A combined function of the Gaussian decay and Lorentz KuboToyabe decay.

A(t)=A_0\left(\frac13+\frac23\left(1-(\sigma t)^2-\lambda t\right)e^{-\frac{(\sigma t)^2}{2}-\lambda t}\right)

where,

\sigma is the KuboToyabe decay rate,

A_0 is the amplitude,

and \lambda is exponential decay rate.
