<li>First select a starting energy (highest γ energy to tag)</li>
<li>First select a starting energy (highest γ energy to tag)</li>
<li>Using [https://halldweb.jlab.org/wiki/images/b/b6/Counterbounds2017%28b%29.xlsx hodoscope energy bin bounds] interpolate the β angle of the first (E<sub>o</sub>) fiber column (β<sub>1</sub>) and the corresponding location on the focal plane (X<sub>1</sub>)</li>
<li>Using [https://halldweb.jlab.org/wiki/images/b/b6/Counterbounds2017%28b%29.xlsx hodoscope energy bin bounds] interpolate the crossing angle with respect to the focal plane (β) of electrons at the center of the first (starting E<sub>γ</sub>) fiber column (β<sub>1</sub>) and the corresponding location on the focal plane (X<sub>1</sub>)</li>
<li>Using β<sub>1</sub> calculate the X<sub>FP</sub> displacement (Δx) from the center of the first fiber column to the center of the sixth fiber column of the first bundle support</li>
<li>Using β<sub>1</sub> calculate the X<sub>FP</sub> displacement along the focal plane (Δx) from the center of the first fiber column to the center of the sixth fiber column of the first bundle support</li>
<ul>
<ul>
<li>Add Δx to X<sub>1</sub> to get X<sub>6</sub>, then interpolate the value of β<sub>6</sub></li>
