Spectral reflectance from 0.35 to 25 μm of original (a) and irradiated (c) meteorite mixture samples. The spectra, normalized at 0.55 μm, are presented in (b) and (d). Samples of different compositions are represented by different colors. Solid lines correspond to fresh samples, while the dashed lines in (c) and (d) represent irradiated samples. In the legend, Aub denotes aubrite, and IM denotes iron meteorite. The same notations are used in all subsequent figures.
