File: P10PLA_V31_FMT.txt Version: 3/19/2001 JFC ------------------------------------------------------------------------- Data Set: Pioneer 10 Version 3.1 Interplanetary Solar Wind Data Sets NSSDC ID: 72-012A-13L DESCRIPTION The files in this and lower directories are derived from the Version 3.1 final archive data sets of the Pioneer 10 Plasma Analyzer. This archive was originally delivered to NSSDC with data files in VMS binary format. In this on-line version all data files have been converted to ASCII format in the same data field sequence as the binary data but with addition of blank spaces between each adjacent data field. In the sub-directories the data files p10plaTT_YYYY.asc from years YYYY = 1972 to 1995 for are for data types TT = HR (hourly average), SM (full resolution summary), and TR (spacecraft trajectory). The ascii files were produced with the FORTRAN codes p10plaTT.for for each data type as above. See the *.SFDU files in this directory, and lower sub-directories, for comprehensive data set, format, and experiment documentation in SFDU format. SUB-DIRECTORIES v31_hour_ascii: Version 3.1 hourly average solar wind data, ASCII v31_summary_ascii: Version 3.1 full resolution summary solar wind data, ASCII v31_traj_ascii: Version 3.1 daily spacecraft trajectory data, ASCII Related Information and Data: Further details on the spacecraft, experiment, data sets at NSSDC, and related WWW sites can be found on the Pioneer 10/11 flight project page under http://nssdc.gsfc.nasa.gov/space/ Hour averages of the interplanetary solar wind data from, and hourly heliocentric coordinates of, Pioneer 10/11 and other interplanetary spacecraft may be also be accessed and plotted on-line through the COHOWeb service based at the same WWW site as above.
