Fig. 9
Spatial variation of footpoint position angle difference, Δφ, from originating ROI pixel locations (see Fig. 10 for value distributions). Scan time increases from left to right, while rows depict values of ΔφLFF−POT (upper), ΔφNLFF−POT (middle), and ΔφNLFF−LFF (lower). A neutral line is plotted in grey for context, as seen in the lower row of Fig. 1.
