Detailed Description

Raw data fitting: Peak Finder.

The Peak-Finder algorithm The amplitude is extracted as a weighted sum of the samples using the best possible weights. The weights are calculated only once and the actual extraction of amplitude and peak position is done with a simple vector multiplication, allowing extremely fast computations.
