This data set includes full resolution
electric and magnetic wave spectra obtained during a ~ 15-minute period of
contiguous observations near the closest approach to Ida and a number of
non-contiguous spectra taken prior to closest approach.

| Data Set Abstract |
This data set includes full resolution
electric and magnetic wave spectra obtained during a ~ 15-minute period
of contiguous observations near the closest approach to Ida and a number
of non-contiguous spectra taken prior to closest approach. In addition
waveform survey data (uncalibrated) and all instrument housekeeping data
are included. 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 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. For the High Frequency Receiver, the time between spectra is
18.67 seconds. Note that the lowest 14 High Frequency Receiver channels
are sampled twice per 18.67 seconds while the remaining channels are
sampled only once. The four Spectrum Analyzer channels are each sampled
7 times in an 18.67 sec interval. |
