This data file has been migrated from PDS3 PRODUCT_ID 122012140SC236DSS45_234
in data set MESS-V/H-RSS-1-EDR-RAWDATA-V1.0 to PDS4. The data file has been sorted according
to data type and a new PDS4 label was created as part of the migration process.

data_to_document
Reference document for the Tracking and Navigation File (TNF) data.
For data collected earlier or later than this document, consult other
document products in the same collection.
IMPORTANT: Records delivered originally by the DSN were in time order, with records for
different TNF data types interleaved. Retaining that structure would have made the PDS
label many times larger than the data file itself. To keep the size of the label
manageable, the original file was sorted so that all records of a single TNF data type are
together. The blocks of homogeneous records were then concatenated -- TNF data type 0,
followed by TNF data type 1, ... followed by TNF data type 17. When there were no records of
a given TNF data type, that block was omitted. Within each block, the records remain in
time order. The label is still long, since each block is a Table_Binary with
many records containing many fields. But there will never be more than 18 blocks and
never more than 18 Table_Binary definitions. The document referenced here correctly
describes the record formats. Note, however, that the records are no longer in absolute
time order. They are in time order within each block and the blocks are ordered by
TNF data type.
