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

This directory includes data and documentation from the Pioneer 11 Helium
Vector Magnetometer (HVM) and Fluxgate Magnetometer (FGM) experiments which are
described briefly in text files P11HVM_NMC and P11FGM_NMC, extracted from the 
NSSDC Master Catalog. FGM provides only data from planetary encounters, while HVM 
provides both interplanetary and planetary data. Brief descriptions and formats 
for each data set may be found in the text (*.txt) files within each subdirectory. 
File MAGCOORD.txt defines the various coordinate systems used for interplanetary 
and planetary HVM data. 
 
The file P11HVM_15M.sfdu provides a detailed description of the Pioneer
spacecraft, the HVM experiment, and the HVM data. This text document is written 
in Standard Formatted Data Unit (SFDU) format as part of NSSDC data set
73-019A-01H for 15-minute averaged data. 


Contents of the various subdirectories are as follows:

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

IP_1HOUR_ASCII - HVM hourly averaged interplanetary magnetic field data

IP_1MIN_ASCII - HVM minute averaged interplanetary magnetic field data

JUPITER_1MIN_ASCII - HVM & FGM 1-minute Jovian encounter magnetic field data

SATURN_1-2MIN_ASCII - FGM 1-2 minute Saturn 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.
