DATA_SET_DESCRIPTION
This data set contains 11 min resolution RTS 16 sector rate, pitch, andphase data for all Jupiter orbits. There are a total of 18 tabulated datafiles that contain A1, A2, A3, A4, A5, E1, F2, TP1, TP2, TA1, TO1, TO2, TO3,TS1, TS2, Start, Pitch, and Phase 16 sector data. The rates reported are inunits of (counts/sec), pitch and phase angles are in (radians).Pitch angle is the angle between the look direction of the detector andthe observed magnetic field. Phase angle is the angle measured from thex-axis to the projection of the look direction onto the xy plane of a localmagnetic coordinate system where the z-axis is the magnetic field direction,the x-axis lies in a plane defined by the direction of corotation and thez-axis, and y-axis complete the set of a right handed coordinate system.Transform Counts/Sec-> Differential Flux:Given the count rate R, pass band of the particle dE, and the geometricalfactor G of the detector it is possible to calculate (dE and G are availablein the EPD instrument template) differential flux j:R/(G dE). For example,given a rate 3000 counts/sec for channel E2, we find in the EPD instrumenttemplate that dE: (0.055-0.042):.013 MeV, G:.035 cm**2 Sr. This gives adifferential flux of 6.59 10**06 (cm**2 MeV s Sr)**-1.This data set is highly discontinuous in time. Because of the severelimitations in the downlink capability of the Galileo spacecraft,data were acquired for only selected portions of each orbit. Duringthe prime mission (first 12 orbits), continuous data were acquiredinside of 50 Rj for all orbits, with a few select orbits havingcomplete or nearly complete coverage in the Real-Time Science (RTS)telemetry mode. During most of the Galileo Europa Mission (GEM) andGalileo Millennium Mission (GMM) coverage was more limited, typicallyonly a few days around perijove, except for the Cassini encounterperiod (orbits 28 and 29) and orbits where recorded data were lostdue to spacecraft safings or other mishaps. Table 1 below providesa listing of the start and stop times of the data for each orbit.Some orbits (5 and 13) have no coverage due to solar conjunctions.Table 2 below provides basic information about the orbits andorbital geometry. After the insertion orbit, which dipped as low asfive degrees south, the Galileo remained within a degree of thejovian equator.----------------------------------------------------------------- Table 1.

CONFIDENCE_LEVEL_NOTE
The data in this set is a product of the processing done by the GalileoLow Gain Antenna Processor. Data in this set includes all the data availablefor LEMMS rates with data quality flag 0 (bad) and 1 (good). Rates with adata quality flag of 0 or are not in the current channel map are set to -1.0.All other rates have a data quality flag of 1 including rates of 0.000.The error bars for each rate is calculated from the standard deviation (SD)formula for a distribution of particles following Poisson statistics(n:number of counts) SD:+-n/Sqrt(n).
