Caption: Figure 2.

The evolution of the flux density at the radio spectral peak with time. We color-code this plot by the position of peak frequency. These values are inferred from fitting Equation (4) to the broadband radio SEDs (see Section 5.1.1 for a detailed discussion and Table 3 for the fitted parameters).
