KPL/SCLK MER-1 SCLK File =========================================================================== This file is a SPICE spacecraft clock (SCLK) kernel containing information required for MER-1 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 MER-1 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 MER-1 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 and nominally starts at the J2000 epoch (2000 JAN 01 12:00 ET).
