Information on resource 'Illumination map of 67P'

This service provides illumination maps for comet 67P. The information is given as the cosinus of the angle between the normal to each facet of the comet shape model and the Sun direction. The comet shape model has 100k facets and corresponds to CSHP_DV_130_01_______00200. Maps are obtained for all solar latitudes / longitudes with one-degree step for both, in the comet reference frame (C-G_CK as provided by ESA/PSA and obtained through AMDA amda.cdpp.eu). The code is developed by A. Beth, Imperial College. User can access both numerical values and images of the illumination maps, projected in latitude and longitude.

illu67p.epn_core – queriable through TAP and ADQL
Thanks to the Rosetta mission, we probed the shape of comet 67P / Churyumov-Gerasimenko. During the cruise, observations revealed strong correlations with the illumination conditions of 67P (diurnal and seasonal variations). Thus, it has been necessary to calculate these conditions from the shape model of comet 67P.
