LOFAR images showing the locations of F and H emission sources for two F–H pairs. The white contours, drawn at 0.1, 0.3, 0.5, 0.7, and 0.9 of the peak brightness temperature, represent the F emission, while the colored intensity (displayed with a square-root color scale, as indicated in the colorbar) corresponds to the H emission. The optical solar disk is shown as a dashed white circle. The white and yellow ellipses in the bottom-left corners indicate the restoring beams for the F and H maps, respectively. In both pairs, the F and H centroids are co-spatial within the LOFAR beam; however, the H emission is clearly resolved into two distinct components, whereas the F appears more extended and blended, likely due to the lower spatial resolution and stronger propagation effects at the F frequency.
