******************************************************************************** Cassini Reconstruction C-Kernel Type 3 C-Kernel with rate data Generated by Tom Burk, (818)393-0974, Cassini AACS Operations ******************************************************************************** MSOPCK SETUP FILE: ckernel.setup ******************************************************************************** This is a sample MSOP CK setup file for conversion of a "pre-parsed" Cassini actual attitude data file (originally in the query2plot ECSV format) to a type 3 CK file. The following are meaning of the setup keywords (only for those which are not obvious :-) INSTRUMENT_ID = -82000 NAIF ID orientation for which will be stored in CK file. REFERENCE_FRAME_NAME = 'J2000' Assume that orientation is given with respect to the J2000. ANGULAR_RATE_PRESENT = 'YES' Input file contains angular rates. QUATERNION_NORM_ERROR = 1.0e-3 If | 1 - quaternion norm | > 1.0e-3, input record is "bad" and will not be written to output CK file. ANGULAR_RATE_THRESHOLD = ( 0.01745329, 0.01745329, 0.01745329 ) Absolute value of any individual angular rate component cannot exceed 0.01745329 (1 deg/sec converted to rad/sec) MAXIMUM_VALID_INTERVAL = 16 interpolation over gaps between data points that are longer than 16 seconds will be prohibited. INPUT_TIME_TYPE = 'SCLK' Input time time type is SCLK (can also be UTC) INPUT_DATA_TYPE = 'MSOP QUATERNIONS' 'MSOP QUATERNIONS' means conjugated (or non-SPICE format) quaternion. Program can also deal with SPICE quaternions, Euler angles and matricies. ANGULAR_RATE_FRAME = 'INSTRUMENT' This tells the program that angular rate vector is given in the s/c body frame (rather than J2000 frame.) See MSOPCK User's Guide for more details.
