Figure 5. Maps of the twelve <strong>fluorescence</strong> signals (the excitation-emissionmatrix). The 5 levels of the scale reflect a classification of the signal (inmV) based on 20 th percentiles. Maps are oriented with the North on thetop. The signal of yellow reflectance under red-orange excitation wassaturated on half of the plot and therefore not usable.15
