Solar Wind Ion Composition in 3.5-hour Averages from the Ulysses SWICS 
Experiment

The following information describes the format of data files for time 
averaged cruise data at 3.5 hour intervals, not including the Ulysses 
flyby of Jupiter, from  the Ulysses Solar Wind Ion Composition 
Spectrometer (SWICS) experiment.

These data files have been copied for public release through NSSDC from 
the Ulysses Data System (UDS) at ESA/ESTEC. Release of UDS-held data 
through 1995 has been authorized by the SWICS Principal Investigator, 
Prof. J. Geiss of the University of Bern, Switzerland. 

The data file name gives the starting year (yy) and day of year (ddd) 
of each file as SWIyyddd.ASC, all written in lower case.

Please acknowledge the NASA National Space Science Data Center and the 
SWICS Principal Investigator for any use of this data in publications.
