Left: phase ψ(ν, r) of dF/ dr fluctuations when seen face-on ( = 5°) for . Note that we deviate from prior figure layouts and use a linear frequency scale here in order to resolve small-scale features. In addition, we show only the lower half of our frequency range. The dashed curve is the local inflow rate ν _inflow. Right: the linear, periodic color map used to generate this figure.
