Analysis
Relative calibration to reflectance factor: division of the raw spectrum by the spectrum of a Spectralon plate recorded in the same conditions at a different time. The spectrum is obtained by averaging all pixels within the outlined Regions Of Interest. The VIS and NIR parts are acquired and calibrated independently and then merged at 940 nm to produce a single VIS-NIR spectrum.
