Thickness
200.0 $\pm$ 100.0 ${\mu}m$
Diameter

Mass
0.098 $\pm$ 0.001 $g$
Substrate material
KBr
Substrate comments
KBr substrate ~ 2 mm thick, 13 mm diameter. The KBr is used as a substrate to avoid meteorite pellet break.
Comments
Pellet prepared by pressing (7 tons for 10 min) 98 mg of the original dust (grain size 1–100 µm) on top of a KBr substrate pellet. The KBr is used as a substrate to avoid pellet break. Thickness of the meteorite pellet is large enough (>200 µm) to avoid contribution of KBr to the spectra.
