There are two methods available for analysing the photon spectra.
<br><br>
<b>spike-width method:</b>
<br>
This method reconstructs the pulse duration from the width of the spectral spikes. For each spectra first an adaptive <a href="page2.html"> low-pass filter</a> is applied to fiter out the noise. Then the position and the number of the peaks in the filtered spectrum are found with a <a href="page3.html">peakfinder</a>. As a last step the spectrum is sliced into different regions and each region is fitted with a Gaussian model to obtain the spike width. Within this method noisy shots are automatically sorted when certain <a href="page4.html">thresholds</a> are exceeded.
<br><br>
<b>auto-correlation method </b>
<br>
This method reconstructs the pulse duration by fitting the auto-correlation function of the data-set with Gaussian model. Furthermore this method can reconstruct the resolution of the spectrometer from the fitting parameters.
