2D configuration for FSS-W (top) and FSS-E (bottom). The slice of the comet is represented in color (red for the FSS-W – blue for FSS-E); north is approximately toward the viewer. The black dot shows the lander location. The successive locations of the orbiter during these sequences of the FSS are represented in black, and the dotted lines show the variations of the orbiter apparent angular locations (θ) for each of these sequences.
