DAWN GRAND MAP CERES IRON MAP V1.0
A global map of the concentration of iron within the regolith of asteroid 1 Ceres on twenty-degree quasi-equal-area pixels is provided. Iron concentrations were determined from gamma ray counting data acquired by Dawn's Gamma Ray and Neutron Detector (GRaND) in a low altitude mapping orbit, about 385 km from Ceres' surface (about 0.8 body radii altitude). The concentrations are representative of Ceres's bulk regolith to depths up to a few decimeters with a spatial resolution of about 600-km full-width-at-half-maximum of arc length on the surface. The methods used to determine iron concentration are described by PRETTYMANETAL2017.
