    • This property of the HRD becomes crucial in regions of high particle density (parts of the E ring and in the vicinity of its source satellites) where the impact ionization detector of the CDA is saturated.

    • Early decoupling of gas and dust is in accordance with the reported low gas densities [Knudsen regime (5)] found in the gas plume (6), making molecule-dust collisions unlikely during the time (tens of minutes) from ejection to the impact of the grain at the HRD.

    • Perturbation forces (Saturn's oblateness, Lorentz force, and radiative forces) are crucial for the long-term dynamics of the particle and the configuration of the E ring (22-26). They can be neglected for the simulation of dust in the vicinity of Enceladus.
