The Visual and Infrared Mapping Spectrometer (VIMS) instrument
onboard the Cassini spacecraft observed the system of Saturn,
acquiring spectral cubes in the range 0.4-5.2 microns. This service
focuses on Saturn satellites, and provides access to calibrated and
ancillary data, computed as described here:

direct links to a larger web site with previews.

Description:
The VOccDB database provides prediction and parameters of stellar
occultations by the main planetary satellites. Observations of a
stellar occultations help to better determine the size and the shape
of the occulting body, as well as its astrometric position at the
milli-arcsecond level precision. Only the main moons of giant planets
Jupiter, Saturn, Uranus and Neptune are considered in the event
prediction database. Predictions are provided over period 2023-2032,
up to visual magnitude 12 for the biggest satellites, and magnitude 14
for other satellites. For each stellar occultation event prediction,
the database provides circumstances and observational data, date and
timing of the occultation, star position and magnitude, excepted
duration, etc.
This service provides the physical and dynamical characteristics of
natural satellites in the Solar System: size, mass, rotational
properties, magnitude and albedo, orbital elements. These quantities
are taken from various publications listed under the bib_reference
parameter. These data will be updated as new values are published.
This service provides a compilation of spectra of asteroids in the
visible and NIR range. It is composed of various libraries distributed
as VizieR catalogues. Reformatted VOtable or fits versions are
provided with thumbnails. Ephemeris data are retrieved from Miriade
(IMCCE) for the reference date when possible.
This service provides a compilation of global spectra of planets and
satellites in the visible and NIR range, for quick reference purpose.
It is made from various libraries, including the
Tohoku-Hiroshima-Nagoya Planet Spectra Library (Lundock et al 2009)
and spectra from a USGS web site (R. Clark). Reformatted VOtable
versions are provided together with links to the original data.
