Analysis
raw biconical reflectance spectrum calibrated in relative reflectance with "matte gold plate" measured under same geometry assuming flat spectral reflectance over the whole 7500-540 cm-1 range. Residual water vapor lines (between 1750-1400, 3900-3550, 5500-5200 cm-1) and CO2 vapor lines (around 630-700 and 2360-2300 cm-1) can be observed.
