NOTE = "Image Index Table containing
Mars Digital Image Map information. The ODL object descriptions
in this file describe the data fields in each row of the table.
The table contains one row for each image file on this CD-ROM
volume set. 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 double quotation marks. 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 that support this
file type and as a normal text file on other hosts."
