Timeline of the the data coverage and of the main results deduced at different wavelengths. From top to bottom, first panel: timeline indicating the GOES X-ray peaks (green arrows; the greater green arrow indicates the time of the peak of the X3.8 flare, while the red arrows indicate the back-extrapolated take-off times of the CMEs). Second panel: data coverage during the LDE (the dotted-continuous line indicates radio data acquired in the range 0.8−2.0 GHz; the dotted line indicates radio data at 3 GHz; the continuous line indicates the H_α data coverage (there are two gaps: 09:50−09:58 UT and 10:07−10:25 UT); the broken line indicates the 1600 Å TRACE data coverage; the lines with arrows indicate the RHESSI HXR coverage). Third panel: time intervals relevant to the three filament destabilization or eruption; the magenta arrows indicate the times of the eruptions of filaments 2 and 3. Fourth and fifth panels indicate with symbols the main emission in the HXR and radio ranges, respectively (see text).
