Description

This description was generated automatically using input from the Planetary Data System. 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: ----------------------------------------------------------------Table 1.

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) ---------------------------------------------------------DUBL 17.0 - 18.0 TRPL 18.0 - 24.0 WDSTP 30.0 - 48.0 WSPL1 30.0 - 48.0 WDPEN 48.0 - 185.0 WPNL1 48.0 - 185.0 SLETB 2.4 - 4.8 DLETB 4.8 - 6.4 TLETB 6.4 - 17.5 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 ------- -------- ------ ------DateTime Spacecraft Event Time (SCET) %24s UTC Derived from PB (Playback) level0 telemetry header data format: %4d-%02d-%02dT%02s:%02d:%06.3f example: 1995-12-07T15:30:08.439Z Mid.Time SCET - Describes the mid %10.6lf 341.652802 End.Time and end time of the data 341.659673 integrated period (decimal day). dMin Duration of integration period %9.4f 19.9886 in minutes.
