Dawn Mars Flyby - GRaND

Raw (Level 1a) Data:

The GRaND EDR 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. The EDR is an intermediate data product derived from the raw data records using reversible operations. All higher order data products are derived from the EDR. An automated pipeline is used to process the EDR from the raw data records.

This data set covers the Dawn GRaND Level 1A data from the Mars flyby.

Calibrated (Level 1b) Data:

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.

This data set covers the Dawn GRaND Level 1B data from the Mars flyby.
