Illumination maps of 67P

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 ( 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.
