After paramater optimization with the extended fit function the same signal is fitted with a line. For both models the corrected Akaike Information Criterion (AICc \cite{Burnham_2004}) is calculated and the region is accepted only if the AICc for the fit function is less than the AICc for the line. This ensures that the goodness of the fit obtained with the fit function justifies the use of a more complicated model.  All *k* events detected in pixel *i* are represented by vectors \(\mathbf{p}_{i,k}\). These vectors can be stacked to make a event matrix for pixel *i*:  \[  E' =   \left(  \begin{array}{l l}  \mathbf{p}_{i,0}\\  \mathbf{p}_{i,1}\\  \ldots\\  \mathbf{p}_{i,k}  \end{array}    \]
