KPL/SCLK

C1XS Fictional SPICE SCLK Kernel
--------------------------------------------------------
 
   This file contains the data necessary for converting from ET to
   ticks for the fictional C1XS spacecraft clock (clock ID code 238.)
 
   This fictional clock begins at 2003-271T00:02:17.001 TDB and contains
   the following discontinuties:

       Time (TDB)                Reason for Partition
   ---------------------   ------------------------------
     2007-001T00:00:00   Chandrayaan EGSE base time   


   The clock has a granularity of 1/65536th a second.
 
   This SCLK is intended for study purposes and for those situations of
   data analysis, until a real clock is not available for the Chandrayaan-1
   spacecraft, to retrieve its orientation that has been modeled as a 
   CK.

Implementation notes
--------------------------------------------------------
 
   This SCLK file is constructed so that the valid SCLK strings are
   simply the number of whole TDB seconds that have passed since the
   Ephemeris epoch corresponding to the last reset of the clock,
   followed by the fractional seconds expressed as the count of
   1/65536th of a second. The start Ephemeris epoch corresponds to the
   time at 1 Jan 2007 at 00:00.
 
   For all time, the clock runs at the same rate as TDB. This 
   circumstance makes the clock only usable for retrieving
   data from the CK file and NOT USABLE for any ACCURATE time
   conversion from UTC to On-board clock or vice versa.

   NOTE: By using this kernel to perform conversions from UTC to
   On-board clock or vice versa, an incertainty of +/- 1 second will
   be introduced in the obtained results.
 
   You must load this file into the kernel pool before using any of the
   SPICELIB SCLK routines. The code fragment
 
      CALL FURNSH ( < name of this file > )

   performs this task. To convert between ET and UTC, you will also
   need to load a leapseconds kernel. The additional call to FURNSH,
 
      CALL FURNSH ( < name of your leapsecond file > )

   will accomplish this. Note that you must supply the actual names of
   the files used on your system as arguments to LDPOOL. Because the
   file names are system dependent, we do not list them here.
 
   For more information, consult your SPICELIB required reading files.
   The following areas are covered:
 
      SCLK system                     SCLK required reading
      Time systems and conversion     TIME required reading
      Kernel pool                     KERNEL required reading
