DATA_SET_DESCRIPTION 
Overview:
=========

This data set provides energetic (MeV) ion fluxes for a variety of
different Z values (carbon, oxygen, sulfur) derived from the
Heavy Ion Counter (HIC) instrument on the Galileo spacecraft. The
data set covers the entire Jupiter orbital mission (December 1995
to November 2002), however, compositions can only be derived from
the LPW (recorded, high resolution) data. Data were recorded during
the followind time intervals:

The data taken during the Io/Jupiter orbit 0 phase and are included in
this data set for completeness (originally released by PDS as
data set ID: GO-J-HIC-4-SUMM-I0ENERGETICIONCOMP-V1.0).

These data are derived from high time resolution data that were
recorded to tape and then playback after the Probe data return. Files
in this data set are stored as ASCII files, giving tables of fluxes
as a function of time.  Appropriate information concerning the
operation 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 the
raw data obtained from the Query Server at JPL.  The composition files
are a high level product where the event data for a given Z range
(corresponding to carbon, oxygen or sulfur) are binned over a time
interval and converted to a flux using the livetime and geometry factors
available in the event files.  Fluxes are determined for each event type
separately since each type responds to a different energy range.  These
are given in MeV/nucleon (for oxygen) below:

Event Type                 Energy Range (MeV/nuc for oxygen)

Ancillary Data:
===============

There are no ancillary data uniquely associated with the HIC
composition data archive. However, the spacecraft trajectory and
attitude data, and the As-run Spacecraft Events Files that are
provided on the same archive volume as these data are useful
ancillary products for users of the HIC data.

Coordinate System:
==================

These are scalar data.

Software:
=========

There is no software provided with this archive.

Media/Format:
=============

Composition data are stored as a simple ASCII data table in the
DATA/HIC directory of the GOMW_5001 cdrom. The first 11 lines of the
original data file consisted of a header that has been moved to the
PDS label (file and data info sections).

Each data line consists of one date/time string and 11 numeric fields.
The integration time (dMin) and the flux fields are floating point.
The count-of-events (cnt) fields are integer and immediately follow
their respective flux field.

The columns are in the following order:

Column
Heading         Contents                        Format      Example
-------         --------                        ------      -------

General:
========

The rate data has been thoroughly checked by the HIC team and includes the
highest resolution data available for this orbit.  The composition data has
been analyzed in detail and consists of our best estimates of the flux of
major ions above 6 MeV/nucleon at a time resolution we believe balances
statistical accuracy with temporal resolution.  Please direct any questions
regarding the generation or interpretation of the data to
PDS_OPERATOR@jpl.nasa.gov.
CITATION_DESCRIPTION Cohen, C., Hamell, G., GO JUP HIC DERIVED ENERGETIC ION COMPOSITION V1.0, GO-J-HIC-5-DDR-ENERGETIC-ION-COMP-V1.0, NASA Planetary Data System, 2000
ABSTRACT_TEXT This data set provides energetic (MeV) ion fluxes for a variety of different Z values (carbon, oxygen, sulfur) derived from the Heavy Ion Counter (HIC) instrument on the Galileo spacecraft. The data set includes all recorded intervals at Jupiter.
