Comparison between S_B-Wind (dashed lines) in W m⁻² Hz⁻¹, as obtained by Waves-RAD1, and (solid lines), as measured by RPW and rescaled by a factor 2/Z₀ for RPW-TNR (black) and RPW-HFR (red) and for the V1-V2 dipole. Vertical dotted lines delimit the data points used to calculate Γl_eff. Panels a, c, and b, d refer to the two type III emissions detected on March 8, 2020, respectively.
