Item Description
SOL A spectrum generated by the spectral unmixing algorithm.
ROI A spectrum calculated for a user-selected ROI.
LIB A user-selected library spectrum. The library includes spectra obtained of
different sources obtained using excitation and emission filters.
Name The spectrum identifier used by the unmixing algorithm. The name
cannot be modified.
Label The spectrum name in the spectrum plot key. The label can be edited.
Color The color of the spectrum in the spectrum plot. For the SOL type
spectrum, it is also the color in the composite image.
Spectrum Preview Shows the spectrum selected above (click a row above the preview
pane).
Use this tool to pick up a pixel in an opened image and plot the spectrum
at this pixel in the spectrum preview.
The Results tab in the Spectral Unmixing tool palette shows the optimized fit
parameters used by the software to derive the spectral unmixing results (Figure 8.2).
