MESSENGER E/V/H GRNS 5 GAMMA RAY SPECTROMETER DAP V1.0

Abstract ======== The GRS experiment is a gamma-ray spectrometer designed to observe spectra of gamma rays emitted from Mercury's surface in the energy range from 0.1 to 10 MeV. This data set consists of the MESSENGER GRS advanced data products (DAPs), which are jpeg2000 maps of gamma-ray count rates or elemental abundances derived from summed GRS data, each with a corresponding one standard deviation error map.
