Emission spectra of the aubrite, lunar, Martian, and ureilite achondrites and the ordinary chondrite Mocs in the 515–535 nm region. Spectra are normalized to unity at 526.95 nm (Fe I-15 line). The Mg I-2 lines in the aubrite spectrum peak at a relative radiance of around 11.5 arb. u. The lines marked by X are artifacts of the Echelle reduction and do not represent meteorite spectral lines.
