Dawn at Vesta - GRaND
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 Vesta encounter.
Calibrated Data (Level 1b)
Status: Certified with minor liens, as of Dec. 12, 2014
The GRaND Reduced Data Records (RDR) contain a time
series of calibrated spectra, counting data, and ephemeris, pointing,
and geometry (EPG) data. The data set is specific to Vesta encounter.
The data volume was certified with minor liens on Dec. 12, 2014. Please
see the liens list for known issues before
using these data.
Level 2 Map Products
This volume includes six data sets, representing higher level GRaND map
products for neutron absorption, fast neutron, high-energy gamma ray counts,
hydrogen abundance, and iron gamma ray corrected and uncorrected counts.
These six maps and their documentation are packaged as a single volume.
