  browse_gdr_l2: Browse images for Level 2 Gridded Data Products
  
  browse_gdr_l3: Browse images for Level 3 Gridded Data Products

  document: Descriptions of the Diviner derived data products 

  document_catalog: Set of PDS3 catalog files 

  miscellaneous: Set of PDS3 index files 

Diviner data were originally archived in PDS using the PDS3 standard, 
which has now been replaced by the PDS4 standard. The RCP and GHRM products 
are new derived products, and therefore they are archived using the PDS4 
standard as new collections in this bundle (urn-nasa-pds-lro_diviner_derived1).
The seasonal PCP product is also a new derived product. It is archived,
along with the newly migrated diurnal PCP product, as a separate collection
using the PDS4 standard. PDS3 labels are included with the migrated diurnal 
PCP products, however the new seasonal PCP products do not include PDS3 
labels.  

The other Diviner derived products that were in PDS3 archives have been moved
to PDS4 collections in this bundle.

Data Products and PDS Labels
============================

Every Diviner data product is accompanied by a PDS label in a file with 
the same name as the data file, but with the extension ".xml", as PDS 
labels are written in XML (Extended Markup Language). The labels may 
be viewed in a text editor or web browser, preferably one that applies 
special formatting to XML files to make them more readable. The labels 
may also be read by software that can interpret XML. 

Documentation
=============
       
The Diviner Reduced Data Record (RDR) Software Interface Specification (SIS) in
the document collection describes the contents, format, and structure of all
Diviner derived data products. As most of these products were archived under
PDS3, the document references both PDS3 and PDS4 components. Currently, the 
revised document has PDS4 updates for the RCP, PCP, and GHRM products.

Text versions of the PDS3 catalog files have also been included in the document
collection to supplement the information in the SIS.

Special Note Regarding GHRM Software Compatibility
==================================================

The Diviner GHRM IMG products and their associated XML files are compatible 
with ENVI version 6.0 and newer. Older ENVI versions may be unable to load the 
IMG products. The current version of ArcGIS Pro (3.2) is also incompatible 
with PDS4 IMG and XML formats.
