Dawn at Ceres - GRaND
Status: ArchivedLatest release date for XMO5-XMO7: May 14, 2019
Raw Data (Level 1a)
The GRaND L1a are a time-ordered collection of gamma ray and neutron counting data and histograms acquired by GRaND during all phases of the Dawn mission. The dataset includes state-of-health data, such as temperature and voltage readings, needed for the analysis of the counting data. This data set covers the entire Ceres encounter.
