  <dc:title>The distribution of H@2.223MeV counts on the lunar surface</dc:title>

  <dc:description>By utilizing the nonlinear least squares fitting and the LM (Levenberg-Marquardt)-BP algorithm to construct two types of spectral inversion models (lunar highlands and lunar maria) are trained to produce this dataset from CE2-GRS data. A map of 2H@2.223MeV counts on the lunar surface is produced by this dataset (spatial resolution 1&amp;deg;x1&amp;deg;). The dataset comprises a total of 65,298 dates. The first column represents the longitude of the location point, the second column represents the latitude of the location point, and the third column represents the corresponding count rate (counts/3s) at each location point. To facilitate graph plotting, values with computed results less than or equal to zero are counted as zero.</dc:description>
