Reflectance Versus Wavelength Plot of 4 Minerals

Reflectance Versus Wavelength Plot of 4 Minerals

Detailed Description

Continuum removal process employed by the Tetracorder spectral feature shape matching algorithm. Three reference spectra are shown: goethite, jarosite and hematite. Each spectral feature has its own continuum end-points (illustrated by the boxes). The continuum is removed from both the observed and reference spectra. For example, the hematite 0.9-µm feature continuum is removed from the Cuprite unknown spectrum, then the goethite continuum is removed, and so on. This allows a specific comparison between each spectral library feature and the unknown. The spectra are offset for clarity.
