| contents | We test on Saturn's rings whether the Hurst exponent is a "robust" observable, in the sense that it returns consistent values for different observations of the same object. We calculate the exponent of the series corresponding to the optical depth as a function of the radius, as obtained from the grayscale value of Cassini pictures, as well as from stellar occultation data from Voyager missions. |
