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).

- Comments
- 20 successive measurements with rotations of 18° between each ((azimuthal angle, varying between 0° and 360°), were average to obtain the reflectance spectrum of an isolated particle. The spot size was adapted according to the size of each samples.
