Caption: Figure 5.
Left: the peak polarized intensity map of the EL observation before applying the median filter. The ripple-like bright patches are presumed to be artifacts of solar interference during observing. Right: the peak polarized intensity map of the EL observation after the application of the median filter with a 120″ box. The median filter is able to completely remove the ripple-like artifacts from the data.
