" END_OBJECT = SPICE_KERNEL \endlabel Deep Impact Flyby Spacecraft SCLK File for Secondary (SCU B) On-board Clock =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for secondary (SCU B) Deep Impact Flyby (DIF) on-board clock to UTC conversion. Production/History of this SCLK file -------------------------------------------------------- This file was created on 2005-07-14; the comments in the file were updated on 2005-09-14 in preparation for archiving in the Planetary Data System. This file was generated by the NAIF utility program MAKCLK, version 3.5.2, from the final DIF spacecraft SCLKvSCET file for SCU B released after the comet encounter. At the time of release this file was named ``DIF_SCU_B_SCLKSCET.00010.tsc''. 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.
