    • DAWN GRAND MAP CERES IRON 7.6MEV GAMMA COUNTS V1.0

    Metadata Updated: December 7, 2023

    A global map of gamma ray counting rates binned on twenty-degree quasi-equal-area pixels is provided. The map was determined from a time series of net counting rates for the 7.6 MeV gamma ray peak produced by neutron capture with Fe within Ceres' regolith. The data were acquired by Dawn's Gamma Ray and Neutron Detector (GRaND) while in low altitude mapping orbit, about 385 km from Ceres' surface (about 0.8 body radii altitude). Prior to mapping, the time series counting data were subjected to corrections for variations in the flux of galactic cosmic rays and measurement geometry, as described by PRETTYMANETAL2017.
