Time span: 1972-03-03 to 1996-10-06
These experimenter-supplied, Jovian charged particle hourly-averaged cruise data in binary format were originally produced on a VAX computer. Each 840-byte record contains spacecraft ID; time in year, day, begin and end day fractions; quarter hour no.; period (60 min); type of data; no. of samples; effective counts; sum of raw counts/0.09375; count rate average (counts/s); standard deviation of count rate; M (Fourier coefficients); K (phase amplitude); phase angle; sum of raw counts; and no. of errors. Various combinations of detectors yield information on 5- to 21-MeV electrons and 30- to 77.5-MeV protons; 0.55- to 21-MeV electrons and 6.6to 77.5-MeV protons; electrons above 31 MeV and protons above 77.5 MeV and electrons above 0.06 MeV. Dates and times were specified with respect to Earth Received Time - UT.
These data are available on-line from NSSDC's FTP site as TAR files, each containing the data from the originally archived magnetic tapes. The are available at:
