when the maximum value is within threshold limits. The default threshold is 4.
Correlation in wavelength space
Wavelength correlation is an example of another wavelength method. During the analysis, the dot
product is calculated between the unknown spectrum and the mean spectrum of each library
product. The unknown is identified as a product when the value is higher than the threshold. The
default value of the threshold is 0.85.
