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
- raw bidirectional reflectance spectrum calibrated: 1) in the 0.4-2.1µm range with "Spectralon 99%" standard (LabSphere (c)) measured under same geometry using its absolute BRDF and 2) in the 2.1-4.0µm range with "Infragold" (LabSphere (c)) using its relative spectral reflectance
