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
   systemize 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.


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

   The following MGS E-kernels are provided on this volume:
   
   -- MGS Spacecraft Sequence EK files:

           No MGS Sequence EK files are included onto this volume because 
           adaptation of the process producing integrated and updated with
           real-time commands Predicted Events Files (PEFs) (which are 
           converted to the SPICE EK format) was not completed at the time 
           when this version of the volume was released. These EKs may be 
           added to the next releases of this volume.

Kernel File Details
===================

   The most detailed description of the data in a text EK file is 
   provided in metadata included inside the description area of 
   the file. This information can be viewed using any text editor
   program.
   
   The most detailed description of the data in a binary EK file is 
   provided in metadata included inside the comment area of the file.
