Comparison of the spectra of the two achondrites - the aubrite candidate (ACH1; in blue) and the eucrite candidate (ACH2; in orange) - with a typical ordinary-chondrite-like spectrum (black). The plots are split into separate wavelength ranges for better visibility, with intensities normalized to unity at the peak of the Fe I line at ≈527 nm. The aubrite candidate spectrum includes a more notable continuum and faint molecular bands of N₂, which can be seen in the bottom two panels.
