This data set includes 1-minute averages of the electric and magnetic
    wave spectra obtained during the period that the Galileo plasma wave
    receiver was operated during the first flyby of Earth.  The parameter
    provided for the electric field spectrum is the electric field spectral
    density in units of V^2/m^2/Hz. The magnetic field spectrum is provided
    in units of magnetic field spectral density, nT^2/Hz.  The spectral
    information is averaged and binned into 49 logarithmically-spaced
    channels from about 6 Hz to 5.6 MHz for the electric measurements and
    34 channels from about 6 Hz to 75 kHz for the magnetic.  Note that these
    'channels' do not generally correspond to the 158 specific channels
    described in the instrument description document. The reduction in
    spectral resolution for this data set was performed in order to make
    the set more conducive to use as a browse data set.   The sources of
    this browse data set are the High Frequency Receiver, Sweep Frequency
    Receiver, and Spectrum Analyzer which make up the Low Rate Science
    portion of the PWS.  During the time interval spanned by this data set,
    Galileo approached Earth from the local early morning sector, made a
    close approach to Earth by passing through the magnetosphere,
    plasmasphere, ionosphere, and finally exited the Earth system in the
    local late morning.

This data set includes all available Low Rate Science spectrum analyzer
    data within the interval of time covered. The data included in this set
    have been checked for accuracy by including only those words from the
    telemetry stream which did not have parity errors based on parity bits
    included with the data as part of the PWS data processing unit functions.
    The magnetic spectra contain narrowband interference lines at 2.4 kHz and
    harmonics.  Missing data are indicated by zero.
