LOFAR radio imaging of the multilane structure, over a background color map representing the coronal Alfvén speed from the Predictive Science MHD model (Riley et al. 2011). Radio contours (80% level) and centroids are shown as in Fig. 4. The dynamic spectrum and lane colors (blue, green, and red) match those in the previous figure. Notably, the central (red) radio source is located in a region of higher Alfvén speed.
