This file (AAREADME.TXT), a PDS volume object definition (VOLDESC.CAT), and the listing of errors and changes (ERRATA.TXT) are included at the root level. The following directories of descriptive material are also at the root level: CATALOG contains descriptive files for cataloging the data on this disc. DOCUMENT contains other documentation. INDEX contains index information (table of contents) on each of the data files included in this disc. All data files on the disc are accompanied by detached PDS labels, which describe their contents. PDS TEXT objects have attached labels. Text files, including data files of ASCII text and all labels (*.LBL files) and tables (*.TAB files), are delimited with carriage-return (ASCII 13) line-feed (ASCII 10) pairs at the end of each line. Detached labels and text files (*.TXT file names) have fixed length records of 80 bytes to facilitate their use as either fixed-length record files or as stream files with carriage-return line-feed delimiters. ============================================================================== SOFTWARE ============================================================================== No software is included with this data set. ============================================================================== PEER REVIEW ============================================================================== This volume is undergoing a peer review by the PDS. The reviewers are undetermined at this time. ============================================================================== CITATION INFORMATION ============================================================================== Users wishing to cite this volume in publications should adopt the following as the method of citation: R.H.
