Figure 14: Power spectrum of the two-way fractional frequency fluctuations (calibrated for plasma
and troposphere) for 2001 – 2002 Cassini solar opposition observations (adapted from [19]). The
spectrum has been smoothed from the intrinsic resolution of the observations to a bandwidth of
3
Hz to reduce estimation error. Representative 95% confidence limits are indicated.
