Multi-Parameter LIBS Reference Database of Geological Materials Bundle M. Darby Dyar Kate Lepore This bundle contains the following collections: data_chemlibs - The data_chemlibs collection contains spectral data from the ChemLIBS instrument. The data are organized by atmosphere (earth, mars, vacuum) followed by laser energy (in mJ). data_superlibs - The data_superlibs collection contains spectral data from the SuperLIBS instrument. The data are organized by resolution (10K or 18K) followed by atmosphere (earth, mars, vacuum) and laser energy (in mJ). data_plibs_z300 - The data_plibs_z300 collection contains spectral data from the pLIBS Z-300 instrument. data_plibs_z903 - The data_plibs_z903 collection contains spectral data from the pLIBS Z-903 instrument. document - The document collection contains a user's guide, a LIBS metadata document, and release notes. Each document and data product in this bundle is described by a PDS4 label in a separate file with the same name 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/. They are best viewed in an XML-aware text editor, and may be used by software that can manipulate XML documents. See these sources for more information. - For information about this bundle, see the document collection in this bundle. - For information about PDS4, see https://pds.nasa.gov/pds4/about/. This bundle was created by Darby Dyar and Kate Lepore and archived at the Geosciences Node of the Planetary Data System. Questions about this bundle may be directed to geosci@wunder.wustl.edu.
