The table is formatted so that it can be read directly into many data management systems. All fields are separated by commas and character fields are enclosed in double quotation marks ("). Character fields are left justified and numeric fields are right justified. Each record ends with ASCII carriage return (ASCII 13). All fields in the tables are fixed width. This allows the table to be treated as a fixed length record file. The PDS label file describes the content and structure of the fields (name, format, brief definition) in the index table The values for start byte listed in the label file include commas between fields or quotation marks surrounding character fields.
