Data Set Overview
  =================
    The MB RDR data products are ASCII formatted tables.  Each ASCII
    table has an associated detached PDS label, also formatted as
    ASCII.  There are several types of MB RDR data products from
    intermediate data reduction to more highly derived ones.  MB
    Summed Spectra RDR products are expressed as summed spectra in
    counts as a function of channel number.
 
    Mineralogical interpretations by the Moessbauer Team of the
    Moessbauer data have been published in the following articles.

  Processing
  ==========
    This dataset uses the Committee On Data Management And
    Computation (CODMAC) data level numbering system to describe the
    processing level of the MB RDR data products.  These data
    products are considered CODMAC Level 4 ['Resampled Data'
    equivalent to NASA Level 1-B].
 
    The MB RDR data products are produced by MB instrument team
    members from the Johannes Gutenberg University (Mainz, Germany)
    using software tools developed by the MB team.  The RDR data
    products - summed spectra in counts as a function of
    channel number - is generated after each sol in which MB data
    were acquired.  This step comprises an extraction of the MB
    spectra from the EDR products and subsequent conversion into
    ASCII formatted tables.
 
    MB RDR data products are generated from binary EDR files that are
    extracted from the OSS to the MB team workstations.  Once RDR
    data products are generated, they are transferred back to the OSS
    for access by other MER science and operations team members.
    After a science validation period, the MB RDR data products are
    transferred to the PDS for final validation and archiving in
    accordance with the MER archive plan.
 
  Data
  ====
    Each MB RDR data file is a table.  The number of columns and rows
    in the table is dependent on the type of RDR.  Columns are
    variable length and are delimited with commas.  Each row is
    terminated with a carriage return and line feed character.  There
    are 6 product types in this data set as described below.  The
    first product type (MGC) is a table of 14 keV (gamma-ray) MB
    spectra as a function of channel number.  The second product type
    (MXC) is a table of 6 keV (X-ray) MB spectra as a function of
    channel number.  The third product type (RSC) is a table of 14
    keV reference spectra as a function of channel number.  The
    fourth product type (DSC) is a table of differential signal as a
    function of channel number.  The fifth product type (ESC) is a
    table of energy spectra as a function of channel number.  The
    sixth product type (ESE) is a table of energy
    spectra in counts as a function of energy.
 
    Velocity calibration files for surface and CCT measurements are
    provided in the CALIB directory of the archive.  These files consist
    of thirteen columns: one per each temperature window.  The
    temperature windows correspond to the temperature windows in the
    MB spectra products (MGC and MXC).  The last temperature window in
    each velocity calibration file contains a room temperature
    extrapolation of the velocity scale.
 
  Software
  ========
    MB RDRs are formatted so that they can be directly imported into
    spreadsheet and plotting software packages.
