Spatial occurrence of the stronger and weaker blue and red excursions with respect to the strong field network regions. Panels a and b: stronger and weaker blue shifted excursions (RBEs) whereas panels c and d: distribution of the stronger and weaker red shifted excursions (RREs/downflowing RREs), respectively. The colors represent the number density of the events shown. The events are mutually exclusive, meaning that the excursions shown in any one panel are unique and are not related to the events in the other. The black contour indicates the regions with an absolute LOS magnetic field ≥100 G.
