ULYSSES HIGH RESOLUTION INTERPLANETARY CRUISE MAGNETIC FIELD DATA
-------------------------------------------------------------------

Data Set Coverage (yyy-mm-dd): 1990-10-25 to 1991-12-31 

Satellite: Ulysses

Experiment: Ulysses Magnetic Field 

Principal Investigator: Dr. A. Balogh, Imperial College, London, UK

Data Set Contact: Joyce Wolf, NASA Jet Propulsion Laboratory

Data Set Description: 

This data set contains high resolution samples at about one-second 
intervals of the interplanetary magnetic field measured by the Ulysses 
Magnetic Field experiment. Field vector components are given in units of 
nanoteslas and in RTN coordinates, where R is the sun-s/c axis, T is the 
cross product of the solar rotation axis and R, and T is the cross product 
of R and T. The field magnitudes in nT are averages of scalar magnitudes 
at higher time resolution. Times are computed at the mid-point of each 
minute  interval and expressed in Spacecraft Event Time - UT (SCET-UT). 
Data gaps have not been flagged in any way - if there were no available 
data in a particular hour then there is no data record for that hour. No 
data from the Feb. 1992 encounter with Jupiter are included. Each file 
includes one day of data. Further details on the magnetic field 
measurements can be found in the following reference: Balogh, A., et al.,
Astron. Astrophys. Suppl. Ser., 92(2), 221, 1992.
