Detailed information regarding its construction follows: References ---------------------------------------------------------- 1. ``C-kernel Required Reading'' 2. ``Kernel Pool Required Reading'' 3. ``Frames Required Reading'' 4. Cassini Frames Kernel Segment #1 ``CASSINI: CAPS_BASE -> CAPS_ART'' ---------------------------------------------------------- This segment contains information necessary to connect the frame CASSINI_CAPS_ART with CASSINI_CAPS_BASE for epochs from launch until the first spacecraft clock rollover. Specifics of segment construction: Cassini SCLK Used: cas00054.tsc Start Epoch (UTC): October 15, 1997 Final Epoch (UTC): December 31, 2093 Start Epoch (Ticks): 1.4370326715800E+11 Final Epoch (Ticks): 9.2099343226300E+11 Instrument ID Code: -82821 Reference ID Code: -82822 Since this is a 'zero-angle' rotation, given the way the articulation and base frames are defined, we have the matrix connecting CASSINI_CAPS_BASE to CASSINI_CAPS_ART follows: [ ] [ ] [ ] [ ] [ ROT ] = [ 0.0 ] [ 0.0 ] [ 0.0 ] [ ] [ ] [ ] [ ] Z Y X where [x] represents the rotation matrix of a given angle x about i axis i. The matrix ROT when left multiplied into vectors in the CASSINI_CAPS_BASE frame yields vectors in the CASSINI_CAPS_ART frame. ~NAIF/SPC END COMMENTS~
