- Measurements were made between 400nm and 1000nm.
Definition: incidence and emergence angles are positive with origin at nadir, and vary in same direction. Azimuth origin (increasing clockwise) is for i = e (opposition geometry).

- Analysis
- The camera has been calibrated using a reference panel (10% reflectance, Pro-Lite) in the same geometry and conditions. The average spectrum of the Altered Plagioclase class has been obtained by SAM (ENVI) classification in the VNIR domain.
