This directory contains Ulysses Jupiter encounter ephemeris covering the
period 1992-01-25 to 1992-02-17. Two versions covering the same time period,
but containing slightly different data, are provided. One version was
provided by the Ulysses MAG team (Imperial College/JPL) and includes Ulysses
SEDR derived System III (1965) spherical, and Earth Mean Ecliptic and Equinox
(1950) spherical and Cartesian coordinates. The other was generated at the
PDS/PPI Node (UCLA) and includes Ulysses SPICE derived System III (1965)
spherical coordinates ephemeris only.
The data are stored as 2 ASCII tables, each covering the full encounter
period. These files are named TRJ25_48.TAB (Ulysses MAG team provided data),
and SPK25_48.TAB (PDS/PPI provided data). The characters '25_48' indicate the
days of the year 1992 covered in the data files. Each data file has a PDS
label file (.LBL) which describes the properties of the data file. There are
also two separate format files, TRJDATA.FMT and SPKDATA.FMT, which describe
the record structure of the SEDR and SPICE ephemeris files respectively.
Please refer to the file DATASET.TXT for a more detailed description of data
set contents.

TRJ25_48.TAB
------------
TRJ25_48.TAB can be read according to the FORTRAN format statement:
'(a24,1x,f10.5,6(1x,f8.3),3(1x,1pe15.8))'
Columns in TRJ25_48.TAB:
=====================================================

Any data column in the file TRJ25_48.TAB whose value is -999.999 or
-9.99999999e+10 (or a similar value depending upon column format) is a
missing data value.
SPK25_48.TAB
------------
SPK25_48.TAB can be read according to the FORTRAN format statement:
'(a24,1x,f10.5,3(1x,f8.3))'
