Description

This description was generated automatically using input from the Planetary Data System. This data set includes full resolution electric and magnetic wave spectra obtained during the period for which real time science data was acquired from the Galileo plasma wave receiver during Jupiter orbital operations. The parameters provided for both the electric and magnetic field spectral data are uncalibrated data numbers. Software and calibration tables provided as part of this data set allow for fully calibrated data for the electric field measurements in raw data numbers, voltage at the antenna inputs (V), electric field (V/m), electric field spectral density (V**2/m**2/Hz), or power flux (W/m**2/Hz). The magnetic field measurements can be provided in units of magnetic field spectral density (nT**2/Hz). The sources of these data are the High Frequency Receiver, Sweep Frequency Receiver, and Spectrum Analyzer which make up the Low Rate Science portion of the PWS. During most of the included time interval, the instrument cycled between the electric and magnetic antennas for the Sweep Frequency Receiver and the Spectrum Analyzer. The High Frequency Receiver is always connected to the electric antenna. Hence, for the Sweep Frequency Receiver and the Spectrum Analyzer, the temporal resolution for electric measurements is basically one spectrum per 37.33 seconds. These data are acquired through Phase 2 software and there is only one measurement for each of the Spectrum Analyzer, Sweep Frequency Receiver and High Frequency Receiver channels. The upper six channels of the Sweep Frequency Receiver (which overlap with High Frequency Receiver channels) are not sampled at all. 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.
