摘要：

Microwave imaging data are widely used in analysis of solar flares. To identify essential features and study their behavior, one has to deal with large data sets of hundreds of frames. This allows a single image, a variance map, to represent the overall dynamics of the event. A method is presented that allows investigation of the detected positions of sources in both Stokes I and V using the analysis of variance maps, combined difference images, and total flux time profiles.
