Finding the Data You Want

1. Search Options

• The Accessing Data tab above will provide a link to the data volume

2. Volume INDEX Files

Each volume has an INDEX subdirectory containing several files including:

• INDXINFO.TXT: summarizes the structure and contents of the other two files in the INDEX subdirectory.

Users are strongly encouraged to read an INDXINFO.TXT before working with the INDEX files.

• INDEX.TAB: an ASCII table file with one row for each data file on the volume.

• INDEX.LBL: the detached PDS label file for the INDEX.TAB file. This is a text file giving names and definitions of all the columns in the index.
