  Dataset Overview
  ================
    This dataset contains the Galileo spacecraft trajectory during the
    Earth 2 flyby. The data have been derived from SPICE kernels at a 1
    minute sample rate. The data are provided in both  Geocentric Solar
    Ecliptic (GSE) and Geocentric Solar Magnetic (GSM) coordinates and are
    given in units of earth radii where 1 Re = 6378 km.

    Data Columns:

    time   S/C event time (UT) given in seconds since 1966
    scet   S/C event time (UT) given in the form yyyy ddd mon day
                               hh:mm:ss.sss
    X      S/C position X component in GSE or GSM coordinate <Re>
    Y_gse  S/C position Y component in GSE coordinates <Re>
    Z_gse  S/C position Z component in GSE coordinates <Re>
    Y_gsm  S/C position Y component in GSM coordinates <Re>
    Z_gsm  S/C position Z component in GSM coordinates <Re>


  Coordinate Systems
  ==================
    The Galileo trajectory data are being archived in 2 coordinate
    systems. Geocentric Solar Ecliptic (GSE) and Geocentric Solar Magnetic
    (GSM) are related earth centered coordinate systems. Both the GSE and
    GSM X directions are taken along the Earth - Sun line, positive
    towards the Sun. The GSE Z direction is parallel to the ecliptic
    normal, positive northward, and Y completes the right-handed set
    (towards dusk). For GSM, the X-Z plane contains the Earth's dipole
    moment vector, positive northward, and Y completes the right-handed
    set. GSE coordinates are commonly used for analyzing the solar wind
    near the Earth and GSM coordinates are used when analyzing data
    inside the Earth's bow shock.


  Data Processing
  ===============
    These data have been derived from the PDS dataset:

    'GO-J-SPICE-6-SPK-E2-V1.0'

    The SPK file used to dervied this product was:

    'GLL920818.SPK'


  Data Quality
  ============
    The data have been derived from the Galileo SPICE kernels using well
    tested software from the SPICELIB and GLLSPICE subroutine libraries.
    Each data point is computed using S/C and planetary ephemerides
    computed at the time of the dataset sample (not interpolated)."
