Following on the wavelet denoising of the original signal the peak structures within the burst were identified. This method is similar to the technique of Li & Fenimore (1996). Starting at the beginning of the burst we examine each peak and attempt to find minima on each side which are separated from the maximum by more than a chosen significance level. If the search for minima fails on a peak it is rejected and the search for peaks continues. The algorithm is designed such that the minima finally selected for a given peak are the lowest possible choices.
We further extend the analysis to allow the identification of peaks which are well separated or isolated. The technique is one of simply determining the fraction of the total height which is above the higher minima and then applying a threshold on this fraction, above which peaks are considered isolated.
