\end{array} \right.  \]  The transient consists of three four  phases: zero level before the onset of the transient,  an exponential increase with time constant \(\tau_r\) starging when \(t=\mu-2\tau_r\), a plateau phase of duration \(d\) starting at \(t=\mu\) and an exponential decay with time constant \(\tau_d\) starting at \(t=\mu+d\)  is convolved with a gaussian \(G(\sigma)\) to yield the actual fitting function:  \[
