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 that part of the SPICELIB library or C
   functions that are part of the CSPICE library to provide required
   time system transformation. These subroutines/functions 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 data set.
   
   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.


MGS LS-kernels contained on this volume
=======================================

   The following generic LSK files are provided on this volume:
   
           naif[VER].TLS

   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.
