Now we know the focal plane crossing locations for the first and sixth SciFi columns in our first bundle. Additionally, we know the β angle of the first bundle (noted as &beta<sub>avg</sub> above), which gives us the optimal alignment for each fiber in the bundle to their respective electron's path. The β angles for the first and sixth columns will be off by the same magnitude, but with opposite signs.

At the back-end of the 2 cm. SciFi a misalignment of around 0.03 mm (with respect the the fiber's axis) results from using an averaged β angle for the bundle support location.]]
