The horizontal axis is labeled “Speed U (kilometer per hour)” and ranges from 0 to 500 in increments of 100 units. The vertical axis is labeled “E superscript critical subscript infinity (kilovolts per meter)” and ranges from 600 to 1200 in increments of 100 units. The legend to the left indicates a blue solid line with circular markers for “Nose region”, a purple solid line with circular markers for “Bottom-mid region”, an orange solid line with circular markers for “Roof-mid region”, a green solid line with circular markers for “Tail-bottom region”, and a yellow solid line with circular markers for “Roof-tail region”. The data is as follows: The line for “Nose region” begins at (0, 738), passes through (100, 739), (200, 742), (300, 749), (400, 758), and finally terminates at (500, 770). The line for “Bottom-mid region” begins at (0, 1,148), passes through (100, 1,146), (200, 1,140), (300, 1,125), (400, 1100), and finally terminates at (500, 1038). The line for “Roof-mid region” begins at (0, 825), passes through (100, 825), (200, 825), (300, 825), (400, 825), and finally terminates at (500, 825). The line for “Tail-bottom region” begins at (0, 978), passes through (100, 978), (200, 976), (300, 972), (400, 969), and finally terminates at (500, 963). The line for “Roof-tail region” begins at (0, 612), passes through (100, 612), (200, 612), (300, 612), (400, 611), and finally terminates at (500, 610).
