Angular parameters

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).

Observation geometry: specular
Observation mode: fixed angles
Incidence angle: 12.0°
Emergence angle: 12.0°
Phase angle: 0.0°
Resolution illumination: 6.0°
Resolution observation: 6.0°

Comments: crystal main axis perpendicular to plane of incidence
