PDS4 Bundle for the Mars Exploration Rover 1 (Opportunity) Mini-TES Calibrated Radiance (RDR) Data

This bundle contains MER1 (Opportunity) Mini-TES calibrated radiance data
migrated from the PDS3 volume.

The bundle contains the following collections:

- Calibration data collection located in the calib directory.
- Calibrated data collection located in the data directory and its subdirectories.
- Document collection located in the document directory.
- Miscellaneous collection located in the index directory.
- Ancillary collection 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 products are merged with the PDS3 volume
such that all the PDS3 files and directories are preserved. But not all of
the PDS3 files have PDS4 labels. For example, the files in the catalog and
software directories, along with a few ancillary PDS3 files were not made
into PDS4 products. Thus, users who want access to the PDS3 labels can
continue to use them. Also, most of the MER documentation is archived in a
separate PDS4 document bundle. Therefore, most documents in this bundle are
listed as secondary members in the document collection. See the document
bundle (urn:nasa:pds:mer_documentation) for the most up to date versions of
MER documents.

The original MiniTES Spectral_Qube structure is defined in the PDS4 label as
a binary table because of the presence of suffix bytes at the end of each
spectrum. An array object could not be used because PDS4 requires that data
objects be continuous and the suffix bytes are interlaced with each spectrum.

The MINITES directory of the document bundle contains an Excel file with the
mapping of attributes in the PDS4 label to keywords in the PDS3 labels. Not
all PDS3 keywords have a PDS4 equivalent. For example, PDS3 keywords such as
INSTRUMENT_ID, INSTRUMENT_TYPE are described in the PDS4 label using the
Observing_System_Component class. There are also a few PDS3 keywords that do
not map to any PDS4 atrribute or class. These include TELEMETRY_FORMAT_ID,
TELEMETRY_FORMAT_EXTENSION_TYPE, and TLM_INSTRUMENT_DATA_HEADER. They are,
however, preserved in the PDS3 labels attached to MiniTES data products.

The band number and center wavelength data in the PDS3 label "GROUP=BAND_BIN"
are included in the minites_wavenumber.csv product located in the
data_ancillary collection of each MiniTES bundle. Each MiniTES data product
contain a link to the wavenumber product.

The PDS3 label history records are captured in the Processing_Information
class of the PDS4 label.

The Opportunity Rover is also known as MER1 (spacecraft serial number) and MERB.
