General information about SPICE E-kernels
=========================================

   The purpose of the Events (E) -kernel is to store different kinds of
   the spacecraft and science instrument events related information
   such as spacecraft and instrument commands, status parameters,
   records of spacecraft activities, ground events, and so on, and to
   systematize and provide access to this data in relational data base
   -like fashion.

   The means of an access to the EK data are provided via SPICE Toolkit
   APIs, calls to which can be integrated into user application
   programs. The information regarding how to obtain the SPICE system
   toolkit for a number of languages and computer platforms is located
   in the ``/software'' subdirectory of the main directory of this data
   set.

   To use E-kernels with INSPEKT program, a Leapseconds (LSK) is
   required.

   Refer to the ``ek.req'' and ``inspekt.ug'' documents provided with the
   toolkit to get more information on how to access E-kernel data.


Stardust E-kernels provided in this Data Set
============================================

   The following Stardust binary E-kernels are provided in this data set:

      Spacecraft Sequence EK files:
 
         sdu_crus_XXXX_YY.bes   Spacecraft Cruise Sequence EK files for
                                the primary mission created by
                                converting integrated Predicted Events
                                Files (PEFs) to SPICE EK format using
                                PEF2EK SPICE Utility Program. The XXXX
                                and YY tokens in the file name specify
                                the sequence ID and part of the
                                sequence correspondingly.

      Spacecraft Command Dictionary EK file(s):
 
         sdu_cmdict_vVVVV.bdb   Spacecraft Command Dictionary EK
                                file(s) created from command
                                definitions contained in Spacecraft
                                Command Dictionary database. If this
                                data set contains multiple dictionary EK
                                files, the one with the latest version
                                (VVVV) supersedes all previous
                                versions.
 
   The following Stardust text E-kernels are provided in this data set:

      Experimenter's Notebook EK files:
              
         sdu_navcam_YYYY.ten    E-kernel files containing all notes
                                regarding NAVCAM images taken during
                                the year YYYY of the primary mission, 
                                submitted by NAVCAM team members SDUENB 
                                System operated by NAIF.


Kernel file details
===================

   The most detailed description of the data in a binary EK file is 
   provided in metadata included inside the comment area of the file. 
   This information can be viewed using utility programs COMMNT and 
   SPACIT included into the NAIF Toolkit.
