Function sets the spectral range of absorption features.
Object of class
The tolerance of the band depth which defines a wavelength as a start or end point of a feature. Usually a band depth of 0 or a ratio of 1 indicates feature limits, however, better results are achieved if slightly deviating values are tolerated.
Optional. If passed, result is directly converted into
Absorption features are defined as the area between local maxima in the reflectance spectra.
This function adds the information of the feature limits to the
Thus, it is a pre-processing step to isolate features.
