<h4>Noise thresholds</h4>
|
|
<p>
|
|
The following thresholds can be set to sort out noisy spectra.
|
|
</p>
|
|
<h2 style="color:blue;">Noise to Signal Ratio</h2>
|
|
|
|
Maximal noise to signal ratio of a spectrum considered for analysis. The noise is defined as the rms difference between the low-pass filtered spectrum and the orginal spectrum. The signal amplitude is the maximal intensity of the spectrum.
|
|
|
|
<h2 style="color:blue;">Background to Signal Ratio</h2>
|
|
|
|
Maximal background to signal ratio of a spectrum considered for analysis. The background is defined as the intensity at the edges of spectra window. The signal amplitude is the maximal intensity of the spectrum.
|
|
|
|
<h2 style="color:blue;">Relative Intensity Threshold</h2>
|
|
|
|
Minimal integrated intensity in percentages of the average integrated intensity
