Sizes (major and minor extent [1/e]) and area of radio sources for all three type II bursts studied in the present work: (a) radio sources extended in equatorial direction; (b) radio sources extended in polar direction; (c) area of the radio sources. Different events and data corresponding to their features are shown in different colors. The grey dashed line is a combined power-law fit to the data. The error bars denote the uncertainty in source sizes following the Gaussian fit to the radio sources to estimate their sizes.
