KPL/SCLK MEX SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for Mars Express 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 Mars Express 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 Mars Express 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.
