PDS4 Bundle for the Lunar Prospector GRS Elemental Abundance Estimates

This bundle contains Lunar Prospector data migrated from the PDS3 volume. It
contains elemental abundance estimates derived from the Lunar Prospector
Gamma Ray Spectrometer (GRS) instrument.

The bundle contains the following collections:

- Browse collection located in the browse directory.
- Data collection located in the data directory.
- Document collection located in the catalog directory. It contains
  the PDS3 catalog files.
- Miscellaneous collection for the PDS3 index files located in the index
  directory.

Each product in this bundle is described by a PDS4 label in a separate file
with the same name as the file described by the 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.

Note that the PDS4 labels and other PDS4 products are merged with the PDS3
volume such that all the PDS3 files and directories are preserved. Thus,
users who want access to the PDS3 labels can continue to use them. All data
products have been given PDS4 labels. Some PDS3 files remain but are not
considered part of the PDS4 bundle. For example, aareadme.txt and voldesc.cat
files in the root directory of this bundle. The aareadme.txt file describes
the structure of the original PDS3 dataset. The voldesc.cat is a PDS3 catalog
file for the volume.

This bundle was created and archived by the Geosciences Node of the Planetary
Data System. Questions about this bundle may be directed to
