a) Wideband L emission accompanied with frequency drifting LS patterns. b) Simple quasi linear QS bursts intersecting part of the band of LS emission. For example, a deep crossing occurs around 01:27:43,20. This fragment is zoomed from the white rectangle of panel c). c) Wideband L emission accompanied by LS bursts in the band 16−25.5 MHz, simultaneous with QS bursts occurring above ~25 MHz. d) Two powerful sub-bands of LS emissions zoomed from the green rectangle in c). Resolution: 1 pixel = 16 kHz × 2 ms a), 4 kHz × 1 ms b), 28 kHz × 2 ms c), and 8 kHz × 2 ms d). The yellow and blue segments are plotted just for convenience illustrating the characteristic values of the drift rate.
