One-dimensional brightness temperature distributions at 5.7 GHz. East-west scans of the flare region in intensity (top panel) and polarization (bottom) at 01:37:29 (solid curve) and 01:37:34 (dotted). The moments are marked in Fig. 4. The lower solid curves show the short pulse source as the difference between these scans, recorded before and at the maximum of the pulse. The solid sections of the dotted curves correspond to the remote source (left) and the flare kernel (right). The segments’ length corresponds to the SSRT diagram.
