ABSTRACT_DESC = "NULL" DATA_SET_DESC = " 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. Morris, R.V., et al., Mineralogy at Gusev Crater from the Moessbauer Spectrometer on the Spirit Rover, Science, 305, 833-836, 2004 [MORRISETAL2004]. Klingelhoefer, G., et al., Jarosite and hematite at Meridiani Planum from Opportunity's Moessbauer Spectrometer, Science, 306, 1740-1745, 2004 [KLINGELHOEFERETAL2004]. 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. Media/Format ============ The data set will initially be delivered and kept online.
