<li>Assuming the center of the first fiber column's front face is on the focal plane where E<sub>γ<sub>o</sub></sub> electron passes and the bundle support is placed at angle β<sub>avg</sub>, use the difference between β<sub>avg</sub> and 19.5072<sup>o</sup> to calculate the Y<sub>FP</sub> displacement required to place the focal plane back on the bundle support's pivot point</li>
