[en] The usual ripple transport calculations lead to a nu^-1 scaling of the transport coefficients with collision frequency nu. This paper extends and clarifies this scaling by taking into account the fact that the dominant contributions to transport come from particles in the high energy tail [E approximately (4-6)T], which restricts the nu^-1 scaling range to nu(T) > (E/T)sup(5/2)deltaωsub(d)(T) approximately 100 deltaωsub(d)(T). In addition, transport coefficients are derived in the low collisionality regime where the radial step size is determined by the distance a particle drifts before it ''collisionlessly detraps'' from a ripple well. The maximum transport rate is found to be about two orders of magnitude smaller than usually assumed, primarily because of the restriction of the nu^-1 scaling regime to the much higher collision frequencies.
