Data Set Overview
  =================
    This data set contains processed LP-GRS time-series data that are used
    as the fundamental data for deriving composition measurements of the
    lunar surface using either energy window techniques or the full
    modeling of the neutron and gamma ray transport processes. These data
    have been processed to eliminate bad data as well as to make
    corrections due to time variations in the cosmic ray flux, LP-GRS gain,
    LP-GRS orientation, and altitude above the lunar surface.
 
    For details of the processing applied to this data set, the reader is
    referred to the paper 'Gamma-ray Measurements from Lunar Prospector:
    Time-Series Data Reduction for the Gamma-Ray Spectrometer', Lawrence et
    al. (2004), J. Geophys. Res., 109, E07S05, doi:10.1029/2003JE002206
