Data was gathered from the Isis2 file: iss_parameters.def.1

The Default focal length is not being used, but was left in
from isis2.

The boresight of the instrument has been updated to the center
of the detector.  Previous values were used along with specific
CK rotation angle frames that were propagated from ISIS2.  These
values proved to be incorrect and have subsequently been corrected
so as to use the frames kernel directly as provided by NAIF.  See
below for additional details pertaining to the SPICE frames
kernels as there is some special handling of this kernel.

The Cassini ISS NAC frames kernel is missing one final rotation in its
CK frames hierarchy.  A 180 degree rotation about the detector center
(Z-axis) is required to map into the proper detector orientation.  This
is not included in the NAIF SPICE frames kernel (cas_v??.tf).  The following
frames definition applies the rotation into camera coordinates and must
be the frame used in the ISIS camera model converting from the s/c frame to
the instrument. (KJB, 2009-01-22)

These are the parameters required for writing c-kernels.  Isis will
create ck with the same frame endpoints as the mission ck.  For 
the Cassini spacecraft the ck frame is CASSINI_SC_COORD (-915240), and the
ck reference frame is J2000 (1).
