The data set is specific to Vesta encounter.  The EPG data are       contained in a single file, with an entry for every science data record    acquired by GRaND at Vesta.  Each record has a unique identifier,          spacecraft clock ticks, which is used as a serial number to identify       data from the same record in other files containing spectra and counting   data.  The RDR data set includes a time series of corrected gamma ray      spectra acquired by GRaND's bismuth-germanate (BGO) scintillator.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.dawn-a-grand-3-rdr-vesta-counts-v1.0_ehr7-bkwa", "issued": "2021-05-21", "keyword": ["4-vesta", "dawn-mission-to-vesta-and-ceres"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=DAWN-A-GRAND-3-RDR-VESTA-COUNTS-V1.0", "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": "DAWN GRAND CALIBRATED (RDR) VESTA COUNTS V1.0"}
