KPL/SCLK
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
from the most recent MEX Time Correlation Packet (TCP) data
converted to SCLKvSCET format using TCP2SCET program.
Usage
--------------------------------------------------------
This file must be loaded into the users 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
