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:
Name ID Old name/Synonym

MAVEN_SEP2_AFT_A_ION_S -202169
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 planar
Silicon detectors. Each sensor is a dual, double ended telescope.
The two double ended telescopes in each sensor are designated A and B.
Each 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.
Instrument FOV Definition(s)
----------------------------------------------------------
This section defines the following FOVs with the Sun keep-out angular
extents (41 deg by 50 deg):
ID SHAPE FRAME SIZE1 SIZE2 BSIGHT

-202121 RECTANGLE MAVEN_SEP1 50. 41. +X
-202122 RECTANGLE MAVEN_SEP1 50. 41. +X
-202123 RECTANGLE MAVEN_SEP1 50. 41. -X

-202128 RECTANGLE MAVEN_SEP2 50. 41. -X
-202129 RECTANGLE MAVEN_SEP2 50. 41. -X
and the following FOVs with the science sensitivity angular extents
(31 deg by 42 deg):
ID SHAPE FRAME SIZE1 SIZE2 BSIGHT
------- -------- --------------------- ----- ----- ------
-202161 RECTANGLE MAVEN_SEP1 42. 31. +X
-202162 RECTANGLE MAVEN_SEP1 42. 31. +X

-202168 RECTANGLE MAVEN_SEP2 42. 31. -X
-202169 RECTANGLE MAVEN_SEP2 42. 31. -X
SIZE1 is the full angular extent, in degrees, in the XY plane of the
corresponding instrument frame. SIZE2 is the full angular extent, in
degrees, in the XZ plane of the corresponding instrument frame.
The FOVs are defined in this data block.
