Odyssey GRS Special Bundle
==========================

This bundle contains a set of special derived products originally released on October 1, 2002. These products include 
global maps of neutron flux and portions of gamma-ray spectra showing hydrogen peaks. Figures in Science journal 
articles published in 2002 by the GRS Team were based on these data.

The articles in question are:
- W. V. Boynton et al., Distribution of Hydrogen in the Near Surface of Mars: Evidence for Subsurface Ice Deposits. Science 297, 81-85 (2002). DOI:10.1126/science.1073722
- W. C. Feldman et al., Global Distribution of Neutrons from Mars: Results from Mars Odyssey. Science 297, 75-78 (2002). DOI:10.1126/science.1073541
- I. Mitrofanov et al., Maps of Subsurface Hydrogen from the High Energy Neutron Detector, Mars Odyssey. Science 297, 78-81 (2002). DOI:10.1126/science.1073616

These data were originally made available with PDS3 labels but were not released as part of an official PDS3 volume. 
This bundle includes the original PDS3 labels in addition to new PDS4 labels. 

The bundle contains the following collections:
- One data collection containing six data products (all ASCII tables).

Each product in this bundle is described by a PDS4 label in a separate file with the same name as the original PDS .LBL 
label but with the extension XML. PDS4 labels are XML (eXtended Markup Language) files that conform to the PDS4 
Information Model XML schema at https://pds.nasa.gov/pds4/schema/released/. The PDS4 labels are best viewed in an 
XML-aware text editor, and may be used by software that can manipulate XML documents.

The PDS4 labels for science products were created and archived by the Geosciences Node of the Planetary Data System.
