DATA_SET_DESCRIPTION Overview:=========This data set provides energetic (MeV) ion fluxes for a variety ofdifferent Z values (carbon, oxygen, sulfur) derived from theHeavy Ion Counter (HIC) instrument on the Galileo spacecraft. Thedata set covers the entire Jupiter orbital mission (December 1995to November 2002), however, compositions can only be derived fromthe LPW (recorded, high resolution) data.

Filesin this data set are stored as ASCII files, giving tables of fluxesas a function of time. Appropriate information concerning theoperation of the instrument can be found in Garrard, Gehrels and Stone,Space Sci. Rev., 60, 305, 1992 [GARRARDETAL1992].Processing:===========The data are processed from the event data which are processed from theraw data obtained from the Query Server at JPL. The composition filesare a high level product where the event data for a given Z range(corresponding to carbon, oxygen or sulfur) are binned over a timeinterval and converted to a flux using the livetime and geometry factorsavailable in the event files. Fluxes are determined for each event typeseparately since each type responds to a different energy range. Theseare given in MeV/nucleon (for oxygen) below:Event Type Energy Range (MeV/nuc for oxygen)----------------------------------------------------------DUBL 17.0 - 18.0TRPL 18.0 - 24.0WDSTP 30.0 - 48.0WSPL1 30.0 - 48.0WDPEN 48.0 - 185.0WPNL1 48.0 - 185.0SLETB 2.4 - 4.8DLETB 4.8 - 6.4TLETB 6.4 - 17.5Ancillary Data:===============There are no ancillary data uniquely associated with the HICcomposition data archive.

CONFIDENCE_LEVEL_NOTE General:========The rate data has been thoroughly checked by the HIC team and includes thehighest resolution data available for this orbit. The composition data hasbeen analyzed in detail and consists of our best estimates of the flux ofmajor ions above 6 MeV/nucleon at a time resolution we believe balancesstatistical accuracy with temporal resolution.
