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.

MGS Frame Definitions
-----------------------------------------------
The variables below define the MGS spacecraft, subsystems and
instrument frames within the SPICE Toolkit Frames mechanism.
In order to use "MGS_SPACECRAFT" as the value for the FRAME
argument defining the reference frame for output geometric
quantities in calls to
CKGP
CKGPAV
SPKEZ
SPKEZR
SPICELIB subroutines, or to be able to read CK orientation data
for some MGS subsystem or instrument if these data are referenced
to this frame in the file, these definitions along with the CK file
containing MGS spacecraft orientation must be loaded into the user's
program.
