Dynamic spectra of separated bursts (left panels) and their selected time series (right panels). Bursts are separated according to their characteristic period ranges of 0.07-1.49 s (panel a)), 1.49−3.03 s (panel c)), 3.03−5.83 s (panel e)), 5.83−21.54 s (panel g)), 21.54−40.26 s (panel i)), and for periods >40.26 s (panel k)). The positive and negative parts of the amplitudes (in relation to their mean values) are given in white and black, respectively (left panels). Frequency drifts of 520, 138, and −262 MHz s^-1 as well as 158 MHz s^-1 are marked by arrows in panel i (1, 2, and 3) and k (arrow 4). For a detailed comparison the individual peaks in the radio time series of the original radio dynamic spectrum (in red) and of the separated spectrum (in green) are shown for the selected 5194 MHz in the right panels. To show the fine individual peaks, we selected the time interval of 49−59 s (in panel b)) within the entire 70 s event duration.
