KPL/SCLK Status ----------------------------------------------- This file is a SPICE spacecraft clock (SCLK) kernel containing information required for Mars Global Surveyor spacecraft on-board clock to ET conversion. This file also contains definitions of MGS reference frames. Production/History of this SCLK files ----------------------------------------------- This file was generated by the NAIF utility program MAKCLK, version 3.3, from the most recent Mars Global Surveyor spacecraft SCLK SCET file. Usage ----------------------------------------------- This file must be loaded into the user's program by a call to the LDPOOL subroutine CALL LDPOOL( 'this_file_name' ) in order to use the SPICELIB SCLK family of subroutines to convert MGS spacecraft on-board clock to ET and vice versa and to use MGS frames defined below as reference frames for geometric quantities being returned by high-level SPK and CK subroutines.
