PSP/RFS radio frequency data showing the type III bursts and storm on 2 April 2019. Top panel: normalised Stokes intensity above 18 MHz, second panel: full spectrogram, third panel: significant burst above the background, and bottom panel: frequency of maximum normalised intensity. This interval shows both more classical type III bursts and the weaker more localised features associated with type III radio storms. These data are described further in the text.
