The GRS experiment is a gamma ray spectrometer designed to observe spectrum of gamma rays emitted from Mercury's surface in the energy range from 0.1 to 10 MeV. There are ten GRS EDR data products: the raw spectra data, the spectra data from the shield (2 versions), shield count rate data, the anti-coincident spectra data, the microphonics data, the software rate counter data, the status parameters, the state of the instrument, and a GRS instrument command list.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mess-e-v-h-grns-2-grs-rawdata-v1.0_symk-buan", "issued": "2018-06-26", "keyword": ["calibration", "earth", "mercury", "messenger", "venus"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MESS-E%2FV%2FH-GRNS-2-GRS-RAWDATA-V1.0", "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": "MESSENGER E/V/H GRNS 2 GAMMA RAY SPECTROMETER RAW DATA V1.0"}
