Expanding trends for ν obtained from the simulations. Top left panel: decay times (blue solid points) obtained from the best fit for the radio-γ response, for the simulation with β_exp = 0.1 and ranging ν_obs = [5, 45] GHz. The orange dashed line represents the best fit with first equation of Eq. (25). Top right panel: same as in the top left panel, but for the case of . The dashed line corresponds to the best fit with the second equation of Eq. (25). Bottom left panel: same as in the top left panel, but for Δt^obs. The dashed line corresponds to the best fit with the third equation of Eq. (25). Bottom right panel: trend of as observed in the simulations (solid blue points) compared to the expectation from the individual best-fit trends of and (dashed line).
