Determining uncertainty
The Software provides an estimative of uncertainty on the selected peak region, based on the of a gaussian like , function that is fitted with the least-squares method. The best fit in the least-squares sense minimizes the sum of squared residuals (a residual being: the difference between an observed value, and the fitted value provided by a model).
The complete process can be visualized on the next figure:
The bandwith limited by the estimated uncertainty would look like this:
Pulsed Fraction
The Software also provides the estimative of the pulsed fraction on the selected peak region, given by the equation wich is defined as follows.
