Data Set Information
DATA_SET_TERSE_DESCRIPTION This data set consists of edited browse data originally obtained from the VG1 PRA instrument near Jupiter. Data are provided for 70 instrument channels covering the range from 1.2 kHz to 1326 kHz in uniform 19.2 kHz steps, each 1 kHz wide.
Data Set Overview
    Instrument P.I.     : James W.  Warwick
    Data Supplier       : Michael L. Kaiser
    Data sampling rate  : 48 seconds
    Data Set Start Time : 1979-01-06T00:00:48.000Z
    Data Set Stop Time  : 1979-04-13T23:58:24.000Z

    This data set consists of edited browse data derived from an
    original data set obtained from the Voyager 1 Planetary Radio
    Astronomy (PRA) instrument in the vicinity of Jupiter.  Data
    are provided for 70 instrument channels covering the range from
    1.2 kHz to 1326 kHz in uniform 19.2 kHz steps, each 1 kHz wide.
    Data are included for the period 1979-01-06 00:00:48 through
    1979-04-13 23:58:24.  In order to produce this data set from
    the original raw PRA data, several steps have been taken:

    1. The PRA operates in a variety of modes; data from modes in
       which the receiver does not scan rapidly through its frequency
       range have been removed;

    2. The data have been calibrated as best we know how;

    3. The data have been split into Left Hand Circular (LHC) and
       Right Hand Circular (RHC) components;

    4. The data have been binned into 48-second intervals.

    Thus, values at a given channel are separated in time by an
    increment of 48 seconds; each 48-second time interval has
    associated with it a value for LHC polarization and one for RHC

    During data gaps, the entire record is absent from the data
    set; that is, missing records have not been zero-filled or
    otherwise marked.  Bad data within a record is indicated by the
    value zero, which cannot otherwise occur.

    Each datum is returned as a 16-bit quantity; it represents the
    mean power received in the given channel at the specified time
    and polarization.  The returned quantity is the value in mB
    about a reference flux density.  To convert a returned quantity
    to flux, use the formula:

    flux   = 7.0x10^(-22)x10^(mB/1000) W m-2 Hz-1

Confidence Level Overview
    This data set includes all the available low-rate scanning mode
    data for the frequency range below 1326 kHz for the time
    interval covered.  Known bad data have been set to zero.  Data
    which appear to exceed the Full Scale Deflection (FSD) of the
    instrument (i.e.  the most intense signal which can be measured
    reliably) have also been set to a zero (should they occur).
    Planetary Radio Astronomy (PRA) suffers from interference from
    many other instruments aboard the spacecraft.  No attempt had
    been made to remove these interferences in this data set.  Two
    obvious examples are the 136 and 193 kHz channels which are
    nearly always contaminated by interference.

    The separation into LHC and RHC polarization components is
    performed on the basis of the polarization of the incoming wave
    as perceived by the instrument.  This takes into account
    neither the antenna transfer function nor the spacecraft
    orientation with respect to the source.  In general, the
    mapping of perceived polarization back to emitted polarization
    cannot be solved without a knowledge of both of these factors,
    as well as a knowledge of the type of polarization coming from
    the source region (e.g.  is it linear or circularly

    Most planetary emissions are circularly polarized.  Below is a
    table showing the response of the experiment to a low frequency
    (100 kHz) LHC wave.  The response does not change much up to
    about 5 MHz.

    The coordinate system used is: THETA == 0 is along the MAG
    boom; PHI == 0 is the bisector of the two PRA antennas.  The
    third column is the apparent value of the left hand component
    as perceived by the receiver.  That is, a value of +1.0
    indicates that the incoming LHC wave is correctly detected as a
    pure LHC wave.  A value of -1.0 will be detected as being of
    the correct strength, but incorrect polarity.  A value of, say,
    0.6 indicates that the total energy is split 60% into the
    apparent LHC component and 40% into the apparent RHC
ABSTRACT_TEXT This data set consists of edited browse data derived from an original data set obtained from the Voyager 1 Planetary Radio Astronomy (PRA) instrument in the vicinity of Jupiter. Data are provided for 70 instrument channels covering the range from 1.2 kHz to 1326 kHz in uniform 19.2 kHz steps, each 1 kHz wide. Data are included for the period 1979-01-06 00:00:48 through 1979-04-13 23:58:24.
