FILE_TYPE_NAME:   PnnTRA.DAT
RECORD_TYPE_NAME: Pioneer 10 and 11 trajectory data
RECORD_STRUCTURE: DEC variable length, no control fields.
RECORD_LENGTH:    70 Bytes (two bytes are a DEC-style record length
                  identifier, the remaining 68 bytes are 17 4-byte real
                  words of data).
RECORD_FIELD_MNEMONICS: SCID, YRDAY, MSEC, RSC, ANGL( 2), CSTATE( 6), 
                        VSC, RE, EANGL( 2), RESC
RECORD_SYNTAX:          17 fields per record in the following order:
                        SCID, JYDD, MSEC, RSC, ANGL( 2), CSTATE( 6), 
                        VSC, RE, EANGL( 2), RESC.  There are no 
                        delimiters between fields in the record.  
                        Records are terminated by the standard ASCII 
                        "carriage-return line-feed."
