    • DAWN GRAND CALIBRATED (RDR) CERES COUNTS V1.0

    Metadata Updated: August 23, 2025

    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.
