Three different wavelengths were used: approximately 1 centimeter, 3.5 centimeters, and 13 centimeters.
The results are coded into the above false-color digitally reconstructed image.
In the above image, the color purple indicates regions populated predominantly by ring particles larger than 5 centimeters, while the color green indicates regions with a significant population of small ring particles less than even 1 centimeter.
The white center of Saturn's B-ring indicates that the density of ring particles was too high to make a good determination.
Other radio observations indicate that some ring particles can be as large as several meters across.
