    • Gartrelle et al. IRTF Asteroid Spectra V1.0

    Metadata Updated: August 22, 2025

    This data set is comprised of the VNIR (0.69-2.5 micron) spectra of twenty-five D-type asteroids from varying Solar System locations. The spectra were obtained from NASA/IRTF on Mauna Kea between 2016-2019 using the SpeX instrument in Low-Resolution Prism mode and the 0.8 x 15" slit. Guiding was performed using spillover light from the slit (GuideDog) for targets with apparent magnitude > 15.5. For targets fainter than magnitude 15.5, guiding was accomplished using the MORIS CCD imager.
