   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  = 900
 
         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.
