Pit selected for the study of the influence of initial parameters, and corresponding energy. A: the location of pit 5, and facets sampled on the plateaus, walls, and bottom. B: the energy received at the 15 facets over one complete orbit, averaged over a daily period window. The gray line marks the perihelion. C: the total quantity of energy integrated over one orbit (left) and the maximum reached during the perihelion (right).
