Description

This description was generated automatically using input from the Planetary Data System.

This data set contains 11 min resolution RTS 16 sector rate, pitch, and phase data for all Jupiter orbits. There are a total of 18 tabulated data files 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 in units of (counts/sec), pitch and phase angles are in (radians). Pitch angle is the angle between the look direction of the detector and the observed magnetic field. Phase angle is the angle measured from the x-axis to the projection of the look direction onto the xy plane of a local magnetic 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 the z-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 geometrical factor G of the detector it is possible to calculate (dE and G are available in 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 instrument template that dE= (0.055-0.042)=.013 MeV, G=.035 cm**2 Sr. This gives a differential flux of 6.59 10**06 (cm**2 MeV s Sr)**-1. This data set is highly discontinuous in time. Because of the severe limitations in the downlink capability of the Galileo spacecraft, data were acquired for only selected portions of each orbit. During the prime mission (first 12 orbits), continuous data were acquired inside of 50 Rj for all orbits, with a few select orbits having complete or nearly complete coverage in the Real-Time Science (RTS) telemetry mode. During most of the Galileo Europa Mission (GEM) and Galileo Millennium Mission (GMM) coverage was more limited, typically only a few days around perijove, except for the Cassini encounter period (orbits 28 and 29) and orbits where recorded data were lost due to spacecraft safings or other mishaps. Table 1 below provides a 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 and orbital geometry. After the insertion orbit, which dipped as low as five degrees south, the Galileo remained within a degree of the jovian equator. ----------------------------------------------------------------Table 1.
