LADEE SCL-Kernels

   Version 1.0; September 24, 2014


General Information About SPICE SCL-Kernels
===========================================

   In the SPICE system, Spacecraft Clock (or SCL) -kernel contains a
   set of information required to perform a mapping between Ephemeris
   time (ET) and spacecraft on-board time (SCLK).
 
   The spacecraft clock coefficient information contained in SCLK file
   can be manipulated using the SPICE Toolkit APIs, calls to which can
   be integrated into user application programs. The SPICE system
   toolkit for a number of languages and computer platforms can be
   obtained from the NAIF web site (http://naif.jpl.nasa.gov/).
   
   Refer to the ``sclk.req'' document provided with the toolkit to get
   more information about conversion between ET and spacecraft clock
   times.

                                         involving the actual LADEE
                                         data.


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

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