Mars Exploration Rover Relative Fe Abundance

This data set contains the Fe redox state and relative abundances of Fe according to Fe-bearing phase as measured by the Mössbauer Spectrometers on both MER rovers. The data were provided by Richard V. Morris, NASA/Johnson Space Center, and archived by the PDS Geosciences Node.

Root Directory - Start here for access to the entire volume. 

AAREADME.TXT - Introduction to the archive. Read this first.
VOLDESC.CAT - Description of the volume contents as a PDS catalog object.

DATA Directory - This archive consists of two tables, one for each rover. Each table is accompanied by a PDS label that defines the table columns. The tables are in comma-separated-value (CSV) format, viewable in any text editor and suitable for loading into a spreadsheet program such as Microsoft Excel.

CATALOG Directory - Files in the CATALOG directory are text files containing documentation formatted for reading by humans and by software. The files contain information about the data set, the instrumentation, references, and
personnel involved in archiving the data. See the file CATINFO.TXT for details. These files are called catalog files because they are entered into the PDS Catalog for online searching.

INDEX Directory - The INDEX directory contains a PDS index table for this archive. See the file INDXINFO.TXT for additional details.

  • INDEX.TAB - A list of the products in this archive, their path and file names relative to the root directory, and the product creation time. This file is described by the label INDEX.LBL.

EXTRAS  Directory - The EXTRAS directory in a PDS archive contains ancillary material that may be useful but is not required for the understanding of the archive. In this archive, the EXTRAS directory contains the original Excel spreadsheets as submitted to PDS, which became the basis for the tables in the DATA directory described above. The contents of this directory are described in EXTRINFO.TXT.
