KPL/IK Europa Clipper Magnetometer (ECM) Instrument Kernel ============================================================================== This instrument kernel (I-kernel) contains Field-Of-View (FOV) and other geometric parameter definitions for the ECM instrument. Version and Date ---------------------------------------------------------- Version 0.0 -- June 24, 2020 -- Boris Semenov, NAIF Initial version. References ---------------------------------------------------------- 1. ``Kernel Pool Required Reading'' 2. ``C-kernel Required Reading'' 3. C. Cochrane et al, ``Optimal Spacing of 3 Sensors on 8.5m Booms'', 9 Bay Spacing option, 03/01/2020 Contact Information ---------------------------------------------------------- Eric W.

Semenov, JPL, (818)-354-8136, boris.v.semenov@jpl.nasa.gov 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. Conventions for Specifying Data ---------------------------------------------------------- All names referencing values in this I-kernel start with the characters `INS' followed by the NAIF ID code for the particular instrument detector or keep out zone: EUROPAM_ECM -159400 EUROPAM_ECM_FG1 -159402 EUROPAM_ECM_FG2 -159404 EUROPAM_ECM_FG3 -159406 The remainder of the name is an underscore character followed by the unique name of the data item. For example, the ECM FG1 boresight direction is specified by: INS-159402_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.

ECM FOV Definitions ---------------------------------------------------------- This section defines ECM FG* FOVs intended solely for testing ECM frames. \begindata INS-159402_FOV_FRAME = 'EUROPAM_ECM_FG1' INS-159402_FOV_SHAPE = 'RECTANGLE' INS-159402_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-159402_FOV_CLASS_SPEC = 'ANGLES' INS-159402_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-159402_FOV_REF_ANGLE = ( 4.0 ) INS-159402_FOV_CROSS_ANGLE = ( 1.0 ) INS-159402_FOV_ANGLE_UNITS = 'DEGREES' INS-159404_FOV_FRAME = 'EUROPAM_ECM_FG2' INS-159404_FOV_SHAPE = 'RECTANGLE' INS-159404_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-159404_FOV_CLASS_SPEC = 'ANGLES' INS-159404_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-159404_FOV_REF_ANGLE = ( 4.0 ) INS-159404_FOV_CROSS_ANGLE = ( 1.0 ) INS-159404_FOV_ANGLE_UNITS = 'DEGREES' INS-159406_FOV_FRAME = 'EUROPAM_ECM_FG3' INS-159406_FOV_SHAPE = 'RECTANGLE' INS-159406_BORESIGHT = ( 0.0, 0.0, 1.0 ) INS-159406_FOV_CLASS_SPEC = 'ANGLES' INS-159406_FOV_REF_VECTOR = ( 0.0, 1.0, 0.0 ) INS-159406_FOV_REF_ANGLE = ( 4.0 ) INS-159406_FOV_CROSS_ANGLE = ( 1.0 ) INS-159406_FOV_ANGLE_UNITS = 'DEGREES' \begintext End of IK file.
