Implementation Notes
-------------------------------------------------------------------------------
This file is used by the SPICE system as follows: programs that make
use of this kernel must ``load'' the kernel, normally during program
initialization. The SPICE routine FURNSH loads a kernel file into
the pool as shown below.
CALL FURNSH ( 'frame_kernel_name; ) -- FORTRAN
furnsh_c ( "frame_kernel_name" ); -- C
cspice_furnsh, frame_kernel_name -- IDL
cspice_furnsh( 'frame_kernel_name' ) -- MATLAB
Once the file has been loaded, the SPICE routine GETFOV (getfov_c in
C, cspice_getfov in IDL and MATLAB) can be used to retrieve FOV
parameters for a given instrument or structure.
This file was created and may be updated with a text editor or word
processor.
Naming Conventions
----------------------------------------------------------
All names referencing values in this IK file start with the
characters `INS' followed by the NAIF MAVEN ID number (-202)
followed by a NAIF three digit ID code for SEP or one of
its detectors or components. This is the full list of names
and IDs described by this IK file:
MAVEN_SEP1 -202120
MAVEN_SEP1_FWD1 -202121
MAVEN_SEP1_FWD2 -202122
MAVEN_SEP1_AFT1 -202123
MAVEN_SEP1_AFT2 -202124
MAVEN_SEP2 -202125
MAVEN_SEP2_FWD1 -202126
MAVEN_SEP2_FWD2 -202127
MAVEN_SEP2_AFT1 -202128
MAVEN_SEP2_AFT2 -202129
The remainder of the keyword name is an underscore character
followed by the unique name of the data item. For example, the -202129
boresight direction provided as a part of its FOV definition is
specified by:
INS-202129_BORESIGHT
The upper bound on the length of the name of any data item is 32
characters.
If the same item is included in more than one file, or if the same
item appears more than once within a single file, the latest value
supersedes any earlier values.
Mounting Alignment
--------------------------------------------------------
Refer to the latest version of the MAVEN Frames Definition Kernel
(FK) [3] for the MAVEN structures reference frame definitions and
mounting alignment information.
Instrument Description
---------------------------------------------------------
SEP consists of two separate sensors: SEP1 and SEP2. Each Sensor detects energetic
electrons and ions using Solid State planer Silicon detectors.
Each sensor is a dual, double ended telescope. Each double ended telescope has 2 FOVs:
one primarily intended for electrons and an oppositely directed FOV for ions.
When combined with the adjacent telescope, each sensor sees both ions and electrons
in the forward and aft direction.
