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).

Analysis
Reference spectrum was acquired using a Spectralon standard (with 99% Lambertian reflectance; Labsphere) to calibrate the absolute reflectance of our measurements.
