DAWN GRAND CALIBRATED MARS FLYBY COUNTS V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 18, 2025 | Last Modified: 2025-07-17
The GRaND RDR are a time-ordered collection of corrected gamma ray and neutron counting data and calibrated pulse height spectra acquired by GRaND during all phases of the Dawn mission. This data set is specific to Mars Gravity Assist (MGA), and includes data acquired during Mars approach and flyby. The RDR is a calibrated data set derived from the Experiment Data Records (EDR), consisting of time-series counting rates from which elemental abundances can be determined. Ancillary ephemeris and pointing data needed for analysis and mapping of the time series data are included in the data set.
