→A summary of the spreadsheet calculations is a follows:

<li>Next determine the locations of the bundle support mounting rods in focal plane coordinates</li>

<li>Figure 21 shows the required dimensions for these calculations</li>
<li>For x locations, include x<sub>1</sub> (for E<sub>γ<sub>o</sub></sub> electrons) in addition to the rods' displacement from the front center of the first fiber column</li>

<li>The Excel spreadsheet provides calculations for the corners of the upstream bundle halves for each bundle support. As shown in Figure 26 below, it is easiest to determine the forward rod location from the upstream bundle half corner closest to the magnet.</li>
<li style="padding-bottom: 16px;">The rear support rod is 5.25 inches, see Figure 21, from the forward support rod along the bundle support's longitudinal axis.</li>

This is the starting point for bundle support #1, but the equations are also useful in the Excel file when determining the beginning and end energy range covered by each bundle support.]]
