Light curves of the first subphase with the QPPs. a) RHESSI channel 25–50 keV. b) SSRT profiles calculated from one-dimension scans in intensity for the total flare source at 5.7 GHz, using the north-south arrays separately, and from the kernel (blue) and remote (red) parts of the east-west scans shown in Fig. 5. The kernel and remote values were multiplied by a factor of 4. c) Same as b), but in circular polarization. d) Profile at 17 GHz calculated from the NoRH images. The vertical lines show the moments before and at the maximum of one of the subpeaks used in Fig. 5. e) Size estimates of the 17 GHz source, smoothed over 0.3 s.
