MEX SCLK File
===========================================================================

     This file is a SPICE spacecraft clock (SCLK) kernel containing
     information required for MEX spacecraft on-board clock to UTC
     conversion.


Production/History of this SCLK file
--------------------------------------------------------

     This file was generated by the NAIF utility program MAKCLK, version
     3.5.2, from the most recent MEX Time Correlation Packet (TCP) data
     converted to SCLKvSCET format (see corresponding section of the 
     description for the SCLKvSCET header and MAKCLK setup file).


Usage
--------------------------------------------------------

     This file must be loaded into the user's program by a call to the
     FURNSH subroutine

          CALL FURNSH( 'this_file_name' )

     in order to use the SPICELIB SCLK family of subroutines to convert
     MEX spacecraft on-board clock to ET and vice versa.


SCLK Format
--------------------------------------------------------

     The on-board clock, the conversion for which is provided by this SCLK
     file, consists of two fields:

          SSSSSSSSSS:FFF

     where:

          SSSSSSSSSS -- count of on-board seconds

          FFF        -- count of fractions of a second with one fraction
                        being 1/65536 of a second
