General information about SPICE LS-kernels
==========================================

   In the SPICE system, Leapsecond (or LS) -kernel contains the
   leapseconds and the values of physical constants required to perform
   a transformation between Universal Time Coordinated (UTC) and
   Ephemeris time (ET). Leapseconds usually occur at the New Year or
   the end of June. The user should check with NAIF/JPL regularly to
   keep up to date about leapseconds.
   
   The information in LSK file can be manipulated by a collection of
   FORTRAN 77 subroutines to provide required time system transformation.
   These subroutines are part of the SPICELIB library and can be
   integrated into user application programs. 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.
   
   Refer to the TIME.REQ document 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 about time conversions
   supported within the SPICE system.


Odyssey LS-kernel contained in this directory 
=============================================
 
   The generic LSK files naming schema is as follows:
 
        naifVVVV.tls
 
   where
 
        VVVV       is the version of the file (example: "0007" is
                      version 7);

   If this volume contains multiple LSK files, the one with the latest
   version ([VER]) supersedes all previous versions.


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

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