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.

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.
