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 collection
   of subroutines that are part of the SPICELIB library, the major
   component of the NAIF Toolkit, or using SPICE system utility program
   INSPEKT to browse E-kernel contents. The subroutines can be integrated
   into user application programs while the INSPEKT program can be
   used to view E-kernel information interactively. The SPICE system
   toolkit for a number of computer platforms or information regarding
   how it can be obtained is located in the SOFTWARE subdirectory of
   the main directory of this dataset.
   
   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 or available from the NAIF Node of PDS if SPICE toolkit is
   not included with this data set to get more information on how to
   access E-kernel data.


Stardust E-kernels provided on this volume
==========================================

   The following Stardust binary E-kernels are provided on this volume:

      Spacecraft Sequence EK files:
 
         sdu_crus_XXXX_YY.bes   Spacecraft Cruise Sequence EK files
                                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
                                volume contains multiple dictionary EK
                                files, the one with the latest version
                                (VVVV) supersedes all previous
                                versions.
 
   The following Stardust text E-kernels are provided on this volume:

      Experimenter's Notebook EK files:
              
         sdu_navcam_YYYY.ten    E-kernel files containing all notes
                                regarding NAVCAM images taken during
                                the year YYYY 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.
