Gartrelle et al. IRTF Asteroid Spectra V1.0
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. -

REDDY NEAR-EARTH AND MARS-CROSSING ASTEROIDS
This data set contains low-resolution (R~150) near-infrared (0.7-2.5 microns) spectra of 27 asteroids, 5 Mars-crossing and 22 near-Earth asteroids, observed with the SpeX instrument on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawai'i. This data set archives reduced, calibrated spectra of targets of opportunity observed from 2001 to 2008. -

REDDY VESTA ROTATIONALLY RESOLVED NEAR-INFRARED SPECTRA
This data set contains low-resolution near-infrared (~0.7-2.5 microns) spectra of main belt asteroid (4) Vesta observed with the SpeX instrument on NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawai'i, and reported in Reddy et al. (2011). This data set archives reduced, calibrated spectra that were obtained as part of ground-based characterization of Vesta prior to the arrival of Dawn spacecraft. They have been used for detailed rotationally-resolved mineralogical/compositional analysis. -

Fieber-Beyer IRTF Mainbelt Asteroid Spectra V2.0
The data set contains observations obtained with the NASA IRTF SpeX instrument covering the 0.7 to 2.5 micron near-infrared portion of the spectrum. The data set archives reduced, calibrated spectra which were obtained by Sherry Fieber-Beyer. -

FIEBER-BEYER IRTF MAINBELT ASTEROID SPECTRA
The data set contains observations obtained with the NASA IRTF SpeX instrument covering the 0.7 to 2.5 micron near-infrared portion of the spectrum. The data set archives reduced, calibrated spectra which were obtained and used in Sherry Fieber-Beyer's Ph.D. dissertation at the University of North Dakota and archives reduced, calibrated spectra subsequent 2010. The research focused on asteroids in a zone centered on the 3:1 resonance. These spectra were used to mineralogically characterize asteroids in this zone in an attempt to identify their meteorite analogs. -

IRTF NEAR-IR SPECTROSCOPY OF ASTEROIDS
This data set contains low-resolution, near-infrared (0.8 - 2.5 micron) spectra of asteroids obtained with SpeX at the NASA Infrared Telescope Facility (IRTF) on Mauna Kea. Since it was commissioned in June 2000, SpeX has been the premier instrument for producing high quality near-IR spectra of asteroids. These spectra have been used for both taxonomic studies of asteroids, and for more detailed mineralogical and compositional investigations. This data set archives the reduced, calibrated spectra that have been published in the peer-reviewed literature, and will be regularly updated as more data become publicly available. -

FORNASIER SPECTRA OF M ASTEROIDS
This data set contains reduced composite visual and near-infrared spectra of thirty M-type asteroids, observed over the years 2004-2008 and presented in Fornasier et al. (2010). The spectra were taken with the Dolores and NICS instruments at the Telescopio Nationale Galileo (TNG) in La Palma, with the EMMI and SOFI instruments at the ESO New Technology Telescope (NTT) in Chile, and with the SPeX instrument at the Infrared Telescope Facility (IRTF) in Hawaii. The individual spectra from the various instruments used to produce the composite spectra are also included. -

REDDY MAIN BELT ASTEROID SPECTRA
This data set contains low-resolution (R~150) near-infrared (0.7-2.5 microns) spectra of 90 main belt asteroids observed with the SpeX instrument on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawai'i. This data set archives reduced, calibrated spectra of targets of opportunity observed from 2001 to 2012.
