General information about SPICE SCL-kernels
===========================================

   In the SPICE system, the Spacecraft Clock Kernel (SCLK) contains
   information required to perform a mapping between Ephemeris time
   (ET) and spacecraft on-board time (SCLK).

   The spacecraft clock coefficient information contained in a SCLK
   file can be manipulated by a collection subroutines that are part
   of the SPICELIB library, the major component of the SPICE Toolkit.
   These subroutines can be integrated into user's application programs.
   Information about obtaining the SPICE Toolkit is located in the
   ``software'' subdirectory of the main directory of this dataset.

   Refer to the SCLK Required Reading (sclk.req) document provided with
   the Toolkit or available from the NAIF Node of the PDS, to get more
   information on how to convert between ET and spacecraft clock times.


SELENE SCL-kernels Contained in This Data Set
==============================================

   This data set contains the following SELENE (Kaguya) SCLK files
   (only the leading portion of the file name is shown; the extension
   of all file names is ``.tsc''):

      SEL_M_VV  SCLK file containing clock correlation data for the
                SELENE spacecraft on-board clock, created by the
                SELENE Project Team, where VV is the version number.

   If this data set contains multiple SCLK files for a particular period,
   the one with the latest version (VV) supersedes all previous versions.

   All SCLK files provided in this data set are in UNIX text format,
   with a line feed character (ASCII 10) at the end of the line.


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

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