Example maps of interpolated surface temperature [K] using the Green’s functions for splines in tension. We show a map of the 24 studied locations (top), a 2D visualisation (middle), where the white facets are due to the non-convex shape of the nucleus, and a visualisation in which the locations are projected onto a 3D shape (bottom figures) after interpolation over all the surface regions. Topography lines are overplotted on the maps in black based on the 3D shape model provided by European Space Agency/Rosetta/MPS for the OSIRIS team. In this example, colours represent the surface temperature of the nucleus at around 3.3 au.
