Abstract ======== This data set consists of the MESSENGER GRS calibrated observations (CDRs) and the reduced data product (RDR). The GRS experiment is a gamma ray spectrometer designed to observe spectra of gamma rays emitted from Mercury's surface in the energy range from 0.1 to 10 MeV. There are seven basic GRS CDR data products: the Ge raw spectra data (GRS_CAL_RAW), the anti-coincidence spectra data (GRS_CAL_AC), the shield spectra data (GRS_CAL_SH, GRS_CAL_SH2, GRS_CAL_SH3), the shield count rate (GRS_CAL_SCR) and the engineering data (GRS_ENG). There is one GRS RDR product (GRS_RDR_SUM), a spectral sum of the GRS_CAL_RAW and GRS_CAL_AC spectra.
