Mars Science Laboratory ChemCam Derived Data Bundle This bundle contains MSL ChemCam derived data migrated from the PDS3 volume. The bundle contains the following collections: - Two data collections (data_libs and data_rmi) located in the data directory. - One browse collection located in the browse directory. - Two document collections located in the catalog and document directories. The PDS3 catalog files are located in the catalog directory and the SISs and other useful tables and documentation are in the document directory. - Two miscellaneous collections for the PDS3 index file located in the index directory and the images located in the extras 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, e.g. aareadme.txt, errata.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 errata.txt lists any comments or errors relative to the PDS3 standards through release 34. 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.
