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.
"The growth of the Tharsis volcanic complex on Mars during
Noachian/Hesperian era induced a reorientation of the spin axis of the
planet (true polar wander). This service gives access to a map of Mars
topography before Tharsis formation (Early Noachian) and a map of Mars
topography before true polar wander (Late Noachian/Early Esperian),
from the model described in Bouley, S., Baratoux, D., Matsuyama, I. et
al. Late Tharsis formation and implications for early Mars. Nature

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.
The database contains some outputs of the VCD for the scenarios : {1)
Standard cloud albedo Scenario, solar EUV average conditions ; 2)
Standard cloud albedo Scenario, solar EUV minimum conditions ; 3)
Standard cloud albedo Scenario, solar EUV maximum conditions ; 4) Low
cloud albedo Scenario, solar EUV average conditions ; 5) High cloud
albedo Scenario, solar EUV average conditions available}, at different
positions of latitude and longitude. These VCD outputs are provided as
Votables containing profiles of temperatures, pressures, density and
abundances of main species for altitudes between 0 and 349.5 km from
the surface.
Mars_dust provides a multiannual climatology of Martian airborne dust as measured by various space missions. The retrieved column dust optical depth is mapped for each Martian year and formatted as cubes with time in the 3rd dimension. Two versions are available: irregularly gridded maps, and regular maps produced by kriging. These latter maps are used as column-integrated dust scenarios in the Mars Climate Database (MCD v5). The detailed description of the methodology and dataset can be found in: Montabone et al (2015) Icarus 251, pp. 65-95https://doi.org/10.1016/j.icarus.2014.12.034 ; Montabone et al (2020) JGR-Planets https://doi.org/10.1029/2019JE006111

Description:
The Mars Crater Catalog by S.J. Robbins was generated from THEMIS
Daytime IR and Viking MDIM 2.1 global mosaics of Mars. Craters were
selected using 5 points along the rim. The table is statistically
complete to the diameter of ~1.0 km. The table contains morphologic
and morphometric data for craters with diameter larger than 3 km. The
Prometheus basin has been excluded from the Catalog due to technical
issues.

Pic du Midi de Bigorre in the French Pyrenees is the place where coronagraphic images were first realized, by Bernard Lyot in the 1930s. Since then, the solar instruments at Pic du Midi regularly provide images of the solar disc, solar prominences and solar corona.
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.
<b>GAIA-DEM</b><br/>
GAIA-DEM is a database of Differential Emission Measure (DEM) maps. The DEM is a
measure of the thermal structure of the coronal plasma, representing the quantity of
light emitting plasma along the line of sight, at different temperatures. In GAIA-DEM, the
DEM is modelled by a specific function of temperature, namely a Gaussian of the
logarithm of electron temperature. GAIA-DEM maps are then maps of the DEM
maximum temperature, of the DEM integral (total Emission Measure), and DEM width (in
temperature). These maps are obtained by inversion from the SDO/AIA EUV images in 6
coronal channels (9.4, 13.1, 17.1, 19.3, 21.1, and 33.5 nm). In addition, maps of the χ²
for the inversion are provided.<br/>
GAIA-DEM is available from a specific interface at
<a href="http://medoc-dem.ias.u-psud.fr/">http://medoc-dem.ias.u-psud.fr</a>, as
well as part of the generic MEDOC interface which is currently located at
<a href="https://idoc-medoc.ias.u-psud.fr/">https://idoc-medoc.ias.u-psud.fr</a>.
These interfaces are based on the CNES SiTools2 framework.
GAIA-DEM is also available from IDL and Python scripts, using a specialization of the
generic SiTools2 IDL and Python clients developed by MEDOC.
*** EUV-SYN *** Synchronous synoptic maps of the corona in the
extreme-UV (EUV), built from series of SoHO/EIT observations, in each
of the 4 wavelength bands of the instrument.
Synchronous synoptic maps are maps of the EUV radiance in different
wavelength bands on the full solar sphere, in heliographic
(Carrington) longitude and latitude, where data are taken as close as
possible to a reference time. They capture the state of the corona at
any given reference time by including data taken as close as possible
to this time.
EUV-SYN is available as part of the generic MEDOC interface which is
currently located at https://idoc-medoc.ias.u-psud.fr/. These
interfaces are based on the CNES SiTools2 framework. EUV-SYN is also
available from IDL and Python scripts, using a specialization of the
