Measurements of comet Halley in the spectral channel of IKS on board
the Vega-1 spacecraft. Data are retrieved from the PDS Small Bodies
Node data set (2011 reformatted version) and updated. The data set
consists in 101 tables providing the radiance spectrum of comet Halley
from various distances, plus two composite spectra. For details and
further references, see: Combes M. et al., 1988, The 2.5-12 micron

Description:
Illumination by the Sun of each face of the comet 67P/Churyumov-Gerasimenko based on the shape model
CSHP_DV_130_01_LORES_OBJ.OBJ. The service provides the cosine between the normal of each face (in the same order as the faces defined in the shape model) and the Sun direction; both
numerical values and images of the illumination are available. Each map is defined for a given position of the Sun
in the frame of 67P (67P/C-G_CK). Longitude 0 is at the center of each map. The code is developed by A. Beth,
Imperial College London, UK and the service is provided by CDPP (http://cdpp.eu). Acknowlegment: The illumination models
have been developed at the Department of Physics at Imperial College London (UK) under the financial support of STFC
grant of UK ST/N000692/1 and ESA contract 4000119035/16/ES/JD (Rosetta RPC-PIU). We would also like to warmly
thank Bernhard Geiger (ESA) for his support in validating the 2D-illumination maps.
The IMCCE is a research institute of the Paris Observatory, associated with the CNRS (UMR8028), whose work concerns mainly the dynamic and planetologic studies of the bodies of the solar system and of the terrestrial environment: planets, natural satellites, asteroids, comets, meteoroids and space debris. The IMCCE, through its VO Solar System Portal, places at the disposal of the Virtual observatory its knowledge and its expertise which concern the dynamics and the physics of the bodies of the solar system through databases, ephemeris computation services, tools of simulation, and numerical computation services fully compliant with the interoperability concept of the Virtual Observatory.
Ion data from the Plasma Composition Experiment on ISEE-1 consist of a combination of (a) velocity moments for the four principal magnetospheric ion species H+, He++, He+, and O+, calculated in two different ways (using two different sets of assumptions) and covering the 0.01-0.1 and 0.1-16 keV/e energy ranges, (b) energy-angle spectra for the same four ions plus O++, covering the 0.01-17.9 keV/e range, and (c) mass spectra (<1 amu/e to about 150 amu/e) for four energy ranges, all derived once per each complete energy-mass scan cycle of the instrument, or once each 1- to 20-minute interval, depending on mode of operation, as well as (d) "total ion" moments, derived once per energy scan and assuming total count rate is due to H+ ions (0.1-16 keV).
These hardcopy plots were provided as a supplement to the digital data from the Plasma Composition Experiment (NSSDC data set 77-102A-12I). A subset of the data in the digital data files is plotted in graphical form in a series of booklets, one booklet for each month of data. There are two pages of graphs for each day, and each page has a stack of 7 panels showing the variation of different parameters during the course of a 12-hour Universal Time interval. Panel 1 (top panel) shows densities of He++, He+, and O+ ions, and the "total" ion density (per cubic meter); Panel 2 shows He++/H+ density ratio; Panel 3 shows ion "thermal" energy (eV); Panel 4 shows "thermal" energy density multiplied by 2/3 along with the magnetic pressure (eV/m^3) and field strength (nT); Panel 5 shows ion drift speed (meters/sec) in the GSE X-Y plane; Panel 6 shows magnetic field elevation angle (degrees) relative to the GSE X-Y plane; Panel 7 shows ion drift angle and the magnetic longitude angle.
UCL 2D Jasmin Model of the Jovian thermosphere. The data consists of Jupiter's
thermospheric wind velocity and temperature as function of latitude and
radius. The filename's string xxrj denotes the magnetodisc radius Rmm in
units of Jupiter planetary radii. For details and further

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.

Description:
A catalogue of Mars craters by Lagain et al. (2020), extending the previous
catalogue from Robbins and Hynek (2012, DOI:10.1029/2011JE003966). 185 craters
were added by Lagain, the object IDs are compatible with the previous work.

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
