Unmasking of the spikes in the image of bright stars using polar plots. The top panel shows the output of the polar plot. The x-axis shows the azimuthal angle, and y-axis shows the radius. The white pixels were originally bleeding pixels. The red profile shows the collapsed value at each azimuthal angle. Based on this plot, the angle of the spike was extracted and removed from the masked pixels, shown in Fig. 5(e).
