-------------------------------------------------------------------------------

This directory group includes ASCII data and documentation from the Pioneer 10 
Helium Vector Magnetometer (HVM) experiment which is described briefly in file
P10MAG_NMC, extracted from the NSSDC Master Catalog. Brief descriptions
and formats for each data set may be found in the text files within each 
subdirectory. File MAGCOORD.txt defines the various coordinate systems used for 
interplanetary and planetary HVM data. 

The file P10HVM_15M.SFD provides a detailed description of the Pioneer
spacecraft, the HVM experiment, and the data. This ASCII document is written in
Standard Formatted Data Unit (SFDU) format as part of NSSDC data set
72-012A-01I for 15-minute averaged data. 

Contents of the various subdirectories are as follows:

IP_1MIN_ASCII - minute averaged interplanetary magnetic field data

IP_15MIN_ASCII - 15 minute averaged interplanetary magnetic field data
                 (data ingest pending to this directory)

IP_1HOUR_ASCII - hourly averaged interplanetary magnetic field data

JUPITER_1MIN_ASCII - minute averaged Jovian encounter magnetic field data

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.
