                        Trajectory data for the Voyager 1 Jupiter ingress radio occultation,
                        recovered from NSSDCA Merged Occultation Data.  These are probably
                        from a Voyager 1 trajectory reconstructed within 18 months of the
                        encounter.  There is almost no documentation accompanying the file 
                        in NSSDCA.

                           Initial version of data recovered from NSSDCA and converted to a pair of
                           PDS4 tables.  The data have been reformatted into physical records that
                           are commensurate with the original logical records.  Records are delimited
                           by carriage-return line-feed pairs.  A new PDS4 label has been generated.

                         This file was copied from the external source product with minor
                         reformatting to create two Table_Character data objects.  The first
                         contains one identifying header record; the second contains many
                         data records. Each record is delimited by a Carriage-Return 
                         Line-Feed pair.
