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