From top to bottom and for each event: (A) soft X-ray flux observed by GOES and hard X-ray emission detected by RHESSI (red curve; right axis) when available. (B) Radio flux observed by Wind/WAVES (the white horizontal line marks 30 kHz) and time-height plot of the CME leading edge (dotted curve; right axis). (C) Electron source profile deduced at 2 R_⊙ (gray histogram) and total percentage of electrons (red curve; right axis). The profile has been shifted by +500 s to allow the comparison with the EM emissions. (D) Directional NR electron intensities measured near 1 AU. (E) Mean pitch-angle and range (gray area) scanned by each sector. (F) PADs measured by Wind/3DP normalized to unity in each time interval.
