Whole Sun radio spectra during the different acceleration episodes, as indicated to the right of the curves. Each spectrum is an average over 1 min taken at the midpoint of the acceleration episode. Data compiled from the Learmonth RSTN station (1.4, 2.7 GHz during the entire burst, 8.8 GHz during Episodes 0 and 6, and 15.4 GHz during Episodes 0, 5, 6) and the Nobeyama Radio Polarimeters (2, 3.75, 9.4, 17, and 35 GHz, Episodes 0−5). The flux density (ordinate) is given in solar flux units (1 sfu = 10^-22 W m^-2 Hz^-1).
