PLEASE NOTE: This archive has been migrated from PDS3 to PDS4. The
contents and directory structure of the PDS3 archive have not changed, 
but PDS4 metadata in the form of XML files have been added. 
The file README*.TXT in the root directory has more information.
The file you are now reading, AAREADME.TXT, was written for the original

  MARS EXPLORATION ROVER MOESSBAUER RELATIVE FE ABUNDANCE ARCHIVE

1.  Introduction

This archive contains Mars Exploration Rover Moessbauer Relative Fe Abundance
products for both the MER-1 and MER-2 rovers.  The archive consists
of one table for each rover. Each table has a detached PDS label that 
describes the content of the table.

2.  File Formats

The Moessbauer Relative Fe Abundance products are ASCII tables in comma-
separated-value format. A detached PDS label accompanyies each table 
that describes the content and format of the table.  The tables are
suitable for reading into a spreadsheet program such as Microsoft Excel.

All detached label and document files are stream format files, 
with a carriage return (ASCII 13) and a line feed character (ASCII 10) at 
the end of each record.  This allows the files to be read by the MacOS, DOS, 
Unix, and VMS operating systems.  

The archive organization and the contents of each directory are described 
below.
