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
- bidirectional
- Observation mode
- fixed angles
- Incidence angle
- 15.0°
- Emergence angle
- 15.0°
- Phase angle
- 0.0°
- Observation mode
- single spot
- Resolutions
- 3000.0 ${\pm}$ 1000.0 ${\mu}m$
- Comments
- The collecting spot size is 3–4 mm, larger than the pellet heterogeneity, and thus representative of all constituents of the meteorite (matrix and chondrules).
