Small subset of SHAP7 shape model of 67P/CG featuring a large pit to be used for performance inter-comparison of the view factor calculation method. The pit can be found in the northern hemisphere of the comet (border of Hapi and Seth region). The color scale corresponds to the total F₁₂ view factor for each facet evaluated with the M₄ method, which is used as a reference (true value). In this calculation the effects of the surrounding shape model are not taken into account. However, this should not carry importance for facets inside the pit, which is our main focus in the following comparisons. The bright blue colored facet indicates total view factor below the minimum value of 10⁻⁸.
