- Description:
- 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: https://vims.univ-nantes.fr/info/isis-calibration. It also provides direct links to a larger web site with previews.

- Description:
- Since 1973, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nançay radio telescope. This allowed an evaluation of the cometary water production rates and their evolution with time, as well as a study of several physical processes: the excitation mechanisms of the OH radio lines, the expansion of the cometary atmospheres, their anisotropy in relation with non-gravitational forces, the Zeeman effect in relation with the cometary magnetic field. The Nançay observations of 53 cometary apparitions between 1982 and 2009 are now organized in this database.

- Description:
- The ephemeris were produced by simulating the ejection of meteoroids from the sunlit hemisphere of cometary nuclei, typically from 0 to 3 au, followed by the propagation of orbits of meteoroids in the Solar System, taking into account the gravity of the Sun, the 8 planets, Pluto, and the Moon, as well as the radiation pressure and the Poynting-Robertson drag. Note that asteroid parent bodies were considered as active (i.e. comet-like bodies) even if they are not active today. The showers are predicted when a planet enters a large enough set of meteoroids, at a distance less than typically 0.01 au.
