             Notes on Using the Image Index Table


The Image Index Table contains one row (record) for each image file on
the Voyager Jupiter CD-ROM disk. The table contains a maximum of 2500
rows describing the compressed images on this volume.

The Image Index Table is formatted so that it may be read directly
into many data management systems on various host computers.  All
fields (columns) are separated by commas, and character fields are
enclosed in quotes.  Each record consists of 512 bytes, with a
carriage return/line feed sequence in bytes 511 and 512.  This allows
the table to be treated as a fixed-length record file on hosts which
support this file type and as a normal text file on other hosts.

The structure and content of the Image Index Table are described in the
file VOLINFO.TXT located in the DOCUMENT directory.  A label coded in
the Object Description Language (ODL), providing a formal description
of the Index Table structure, is located in the file IMGINDEX.LBL.

Users of most commercial data management systems should be able to
use the list below to define the names and characteristics of each
field and then to load the table into their data manager using a
delimited ASCII text input format.  If necessary the specific column
start positions and lengths can be used to load the data.

The list below presents each field in the Image Index Table, along
with a 10-character terse name for each field, the full PDS data
dictionary name, the data type which would normally be used for
loading the field into a data management system, the field width and
the number of decimal places in numeric fields.
