\]  For notational purposes we shall represent the fit funcion parameters by \(\mathbf{p}=\left[A,d,\tau{d},\tau_{r},\mu\right]\). The smoothing parameter \(\sigma\) will be fixed for all pixels. Therefore, for the \(i\)-th pixel the \(k-th\) event is represented by \(f(\mathbf{p}_{i,k},t)\).  The entire raw signal for the \(i\)-th *i*-th  pixel is: \[  F_i(t) = b(\mathbf{q}_i, t) + \sum_{k=0}^{m} f(\mathbf{p}_{i,k},t) + W  \]
