Dones, H. C., Deau, E., Charnoz, S., Baker, E., Weiss, J., Porco, C. (2006). "Cassini ISS Photometry of Saturn's Rings." American Astronomical Society, DPS meeting #38, #51.02.

Saturn's main rings are known from Voyager and HST images to display regional variations in particle albedo, color, and phase function. We will present the results of photometric model fits to the first two years of Cassini images of the rings, and will discuss implications for the origin of ring structure.
