The CDPP (Centre de Données de la Physique des Plasmas) was created in 1998 jointly by CNES and INSU
as the French national data centre for natural plasmas of the solar system. The CDPP assures the long term preservation
of data obtained primarily from instruments built using French resources, and renders them readily accessible and
exploitable by the international community. The CDPP also provides services to enable on-line data analysis (AMDA),
3D data visualization in context (3DView), and a propagation tool which bridges solar perturbations to in-situ
measurements. The CDPP is involved in the development of interoperability, participates in several
Virtual Observatory projects, and supports data distribution for scientific missions (Solar Orbiter, JUICE).
Centre de Données de la Physique des Plasmas(CDPP)
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.
