\begin{align*}   \textrm{d}\lambda_t =& -\gamma_{\lambda} (\lambda_t-\mu_{\lambda}) \textrm{d}t + \sigma_{\lambda}\textrm{d}W_t\\  \end{algin*) \end{align*)  Similarly an additive baseline term $B_t$ was added to take into account traces where the signal do not go back to zero. This was necessary to avoid spurious deformation of the phase around the trougth of the signal. The baseline term also follows an Ornstein-Uhlenbeck process.
