Metadata Updated: December 6, 2023

The GRaND Reduced Data Records (RDR) contain a time
series of calibrated spectra, counting data, and ephemeris, pointing,
and geometry (EPG) data. The EPG data are contained in a single file,
with an entry for every science data record acquired by GRaND within the
dataset start-stop times. Each record has a unique identifier,
spacecraft clock ticks, which is used as a serial number to identify data
from the same record in other files containing spectra and counting data.
The RDR data set includes a time series of corrected gamma ray spectra
acquired by GRaND's bismuth-germanate (BGO) scintillator.
