Voyager observations; both the spin pole orientation and spin rate
will probably differ during Cassini's mission. Hyperion radii and

Note that GM values >= 1.0 are packaged as is into 7CONIC_VEC
commands for AACS to propagate the body's ephemeris.
For GM values < 1.0, the value in the G_MASS parameter
of the 7CONIC_VEC command is set to 1.0. One is the minimum
value for the G_MASS parameter. The resetting of the G_MASS
parameter to the minimum acceptable where the actual
GM is < 1.0 is acceptable since CAS will not pass close enough
to any of the affected bodies for the gravitational mass
to have an effect.
-------- OBLATE SPHEROIDS VERSUS TRIAXIAL ELLIPSOIDS
Some Cassini software cannot model triaxial ellipsoids, where the
RADII are all different. Instead, they model bodies as oblate
spheroids, where the equatorial RADII values (the first two) must
be identical. In cases here where the equatorial radii are not
identical, the average of the two should be used when constructing
an oblate spheroid. The polar radius (the third RADII) can be used
as given in both cases.

ADD:
BODY699_RADII_RS = ( 60330. 60330. 60330. )

Date: Tue, 25 Nov 2003 16:22:41 -0700
From: Carolyn Porco <carolyn@ciclops.org>
2002 Oct 01 (published)
Changed BODY699_RADII_OPTICAL to be consistent with recommendation of Phil
Nicholson dated 24 Sep. Added notes in the version history as to which
versions were published to the DOM, as opposed to the versions that were
intermediate for review.
2002 Aug 28
Expanded some version histories. Added radii for alternate models of Saturn.
Added notes on oblate spheroids vs. triaxial ellipsoids. Fixed the reference
for BODY10_GM. Provided more description of URL links.
2002 Aug 12
Added notes on gravitational harmonics. Added link to NAIF required reading
document. Removed unused references.
2002 Jun 21
Made cosmetic changes to organization. Added begindata flag to Venus area
so that Venus data would not be lost. Copied Venus GM to Venus system GM
(since Venus has no satellites). Removed entries for small Jovian
satellites except for Himalia (no small satellites were observed by Cassini
except Himalia). Added dummy orientation values for Himalia (since
IAU_HIMALIA is a possible coordinate frame). Removed last two NUT_PREC entries
for Jupiter (big 4 satellites + Himalia only require 8 angles, not 10). Fixed
the BODY3_NUT_PREC angles to the full set that is required for Earth and Moon
orientation. Corrected errors in the orientation for Callisto and Jupiter.
Removed BODY7_NUT_PREC angles since no Uranian satellites are present.
Adjusted Jovian satellite radii to match IAU 2000 report. Added LONG_AXIS
statement for Hyperion.

-------- FORMATTING FOR SPECIAL PARAMETERS
BODYNNN_GM
GM in km^3/s^2
BODYNNN_RADII_OPTICAL
BODYNNN_RADII_1BAR
BOYDNNN_RADII_RS
Alternate radii that are required for modeling purposes. These radii are
not necessarily identical to the IAU standard, and may have to be updated
during tour at a frequency not compatible with the IAU standard update
process. (For this reason, these were added so that Cassini would not be
required to use the existing RADII for not-IAU-approved values.) The OPTICAL
radii are typically used to determine the point at which Saturn's atmosphere
begins to attenuate light rays (e.g. for shadowing). The 1 bar radii may be
used as a markpoint for some radio or atmospheric observations. The RS radii
may be used by ring scientists that model Saturn as a sphere.
BODYNNN_ATMOSPHERE
Exponential atmospheric model in the form of one set of
two values To, f, followed by any number of sets of
three numbers Do, K, Zo. The atmospheric density in g/cm3
can be calculated as follows:
Z = height above surface (km)
R = radius of body (km)
T = thermospheric temperature (K) = To + f * sigma, where
sigma is the number of standard deviations (conservatism)
desired. If f > 0, positive sigma will result in a hotter
thermosphere and higher density.
H = scale height of atmosphere (km) = T * ( R + Z ) / K
(K is a curve-fit parameter with units of degrees K)
D = density (g/cm3) = Do * exp( - ( Z - Zo ) / H )
If there are more than one set of Do, K, Zo, sum each
value to get the total atmospheric density.
BODYNNN_RING*
The ring identification scheme is numeric with keyword-associated names.
The defnition of a ring is in a set of keywords. The BODYNNN_RING...
keyword set includes
1) a required NAME keyword (BODYNNN_RING<n>_NAME),
2) either a complete ring keyword (BODYNNN_RING<n>) or a set of segmented
ring keywords (BODYNNN_RING<n>_<X>), and
3) optional embedded ringlet/gap keywords (BODYNNN_RING<n>_<n>) with
required names (BODYNNN_RING<n>_<n>_NAME).
The total number of rings (BODYNNN_RING<n>) that can be defined is from
01 to 99. A complete ring can be segmented (BODYNNN_RING<n>_<X>) in upto
26 (A-Z) sub-segments. Embedded ringlets/gaps (BODYNNN_RING<n>_<n>) can
be defined from 1 to 99. Ring geometry is defined in the form of one set
of R1, R2, Z1, Z2, OD where R1 and R2 are inner and outer radii
respectively of the ring (in kilometers), Z1 and Z2 are the vertical
heights of the ring at R1 and R2 respectively (also in km, equal to
one-half of the total thickness of the ring), and OD is the average optical
depth of the ring sub-segment/gap across R1 to R2. A complex ring
thickness model is pieced together by sub-segmenting Rs, Zs, & ODs; each
sub-segment is uniquely numbered.
BODYNNN_*COEF
Where * = J, C, or S. These coefficients are the normalized gravity field
coefficients. J's are 1 to N, C's and S's have two indexes. Index 1 goes from
1 to N, and Index 2 goes from 1 to (Index 1). E.g. C11, C21, C22, C31, C32,
C33, C41, etc.
BODY699_RING7_FCENTER
Elliptical orbital characteristics for the F Ring: The array items (and
units) are (in order):
SEMIMAJOR_AXIS (km)
ECCENTRICITY (degrees)
LONGITUDE_PERICENTER_EPOCH (degrees)
PERICENTER_PRECESSION_RATE (degrees)
INCLINATION (degrees)
LONGITUDE_ASCENDING_NODE_EPOCH (degrees)
NODAL_REGRESSION_RATE (degrees).
The epoch for the elements is J2000 (noon UTC on 1/1/2000) at the ring
(i.e., with no light-time correction). Longitudes are measured in the
prograde direction from the ascending node of Saturn's equatorial plane
on Earth's J2000 equator.
