FIGURE 13.6.4.- Hetegonic effects in the Saturnian ring system. Dollfus' photometric profile compared with Mimas' orbital distance reduced by a factor 2/8 (or 0.65). Cassini's division may be the "hetegonic shadow" of Mimas. In the left comer, the photometric profile is turned upside down. and reduced by the factor 2/3 ("ring's own. shadow"). The rapid drop in intensity between the B ring and C ring coincides with the beginning of this shadow.
