The spectra were obtained from\nNASA/IRTF on Mauna Kea between 2016-2019 using the SpeX instrument in Low-Resolution\nPrism mode and the 0.8 x 15\" slit. Guiding was performed using spillover light from\nthe slit (GuideDog) for targets with apparent magnitude > 15.5. For targets fainter\nthan magnitude 15.5, guiding was accomplished using the MORIS CCD imager.", "identifier": "urn:nasa:pds:gbo_ast-dtype_gartrelleetal_irtf_spectra", "issued": "2021-05-21", "keyword": ["1167-dubiago", "1256-normannia", "1269-rollandia", "1542-schalen", "1583-antilochus", "1702-kalahari", "1746-brouwer", "2207-antenor", "2208-pushkin", "2246-bowell", "2266-tchaikovsky", "2311-el-leoncito", "2357-phereclos", "267-tirza", "2674-pandarus", "2872-gentelec", "2893-peiroos", "3248-farinella", "3283-skorina", "336-lacadiera", "368-haidea", "4744-rovereto", "721-tabora", "773-irmintraud", "884-priamus", "multiple-asteroids", "none"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewBundle.jsp?identifier=urn%3Anasa%3Apds%3Agbo_ast-dtype_gartrelleetal_irtf_spectra&version=1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "Gartrelle et al.
