Figure 2. Examples of the field size opening on the beam's eye view (BEV): (A) the BEV on the start angle of ARC01, (B) the BEV on the start angle of ARC02, (C) the BEV on the start angle of ARC04, (D) the BEV on the stop angle of ARC05, and (E) the three‐dimensional display of six partial arcs. The CW arcs display in red curvature and the CCW arcs in yellow curvature. The corresponding BEVs of A to D are shown in this figure.
