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, 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 References -------------------------------------------------------- 1.
