- 5
- Laboratory
- Institut d'Astrophysique Spatiale (IAS)
- Instrument
- Bruker Tensor
- Sample holder
- The sample is mounted on a vertical holder in the vacuum chamber of INGMAR setup (IrradiatioN de Glaces et Météorites Analysées par Réflectance VIS-IR, IAS-CSNSM/Orsay)

- Incidence angle(s)
- 20.0°
- Emergence angle(s)
- 15.0°
- Phase angle(s)
- 15.0°
- Observation mode
- single spot
- Spatial resolution
- 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).
