4.2 How the spectrum file on logarithmic scale is plotted

 

The Laplace spectra can be plotted in two different ways: Y*X and standard. In the first case the values on the vertical axis of the spectrum represent the contribution (in terms of magnitude) of the given emission rate to the overall transient while in the other case, this contribution is represented by the area under a peak. Both ways of the spectrum plotting can be used either by the main program after the synchronous calculations or by the ExpDBase program where the spectra already calculated are stored. When details of the Laplace peaks are inspected they are independent on the way the spectrum is plotted. When the spectrum is plotted using the first way then the peak amplitude is a sum of values of all spectrum points which form the given peak, in the later case one has to calculate the area under the peak.
