KPL/SCLK Deep Impact Flyby Spacecraft SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for DIF 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 DIF spacecraft SCLKvSCET file (see corresponding section of the description for the SCLKvSCET SFDU 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 DI 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 1/256 of a second References -------------------------------------------------------- 1.
