File: P10MAGJUP_FMT.txt Version: 12/22/98 JFC ----------------------------------------------------------------------------- One-minute Pioneer 10 Magnetic Field Data Within 7 Rj of Jupiter - Dec. 1973 Date/Time Coverage: 1973-12-03/21:50:59 to 1973-12-04/07:54:03 [GRT-UT] NSSDC Data Set ID: 72-012A-01G Data Set Contact: Joyce Wolf, Experiment: Pioneer 10 Helium Vector Magnetometer (HVM) Principal Investigator: Dr. Edward C. Smith, Jet Propulsion Laboratory, Pasadena, CA Description: This directory contains the ASCII data file P10MAGJUP.asc from NSSDC data set 72-012A-01G for one minute jovicentric magnetic field data from the Pioneer 10 Helium Vector Magnetometer (HVM) within 7 Rj of Jupiter during the Dec. 1973 encounter. Times are given in Ground Received Time - UT. The file P10MAGJUP_NMC provides further information on this data set from the NSSDC Master Catalog, Data Format: The data are in JG coordinates, defined as follows: the X axis is in the direction of G, the equatorial vector lying in the System III Prime Meridian, 1957.0; the Z axis is in the direction of J, the spin axis of Jupiter; and the Y axis is parallel to Jupiter's equatorial plane and completes a right-handed orthogonal system. Each record is 80 bytes long, and contains the following data in the format (F7.4, 6F12.4): DTM Ground received time in days (3.0 = Dec. 3, 00:00). (Year = 1973 for Pioneer 10; 1974 for Pioneer 11.) RR Distance of Pioneer from Jupiter, in Jupiter radii. RLTJG Latitude of Pioneer in Jupiter-centered JG system. RLNJG Longitude of Pioneer in Jupiter-centered JG system. BXJG One-minute average of x-component of field in JG. BYJG One-minute average of y-component of field in JG. BZJG One-minute average of z-component of filed in JG. Angles are measured in degrees; fields in gammas.
