NOTES:  4.3  A large number of fibers were found in Box 75, received 11/2, that had a strange curve in them. We guess that this curve came from the way that the fibers were twisted around each other in the storage box.

NOTES:
5.3 PMT 41: L bundle is not split properly around PMT37. PMT33: Laser fiber is wrapped around WLS fiber. PMT11: Laser fiber should be routed below WLS fiber to PMT9. PMT1: Fibers are wrapped around fibers to PMT13. Laser input fibers need to be routed to the other end of girder - Both sides. PMT16: All fibers in L bundle should be under D6 fibers. PMT14: Lost its laser fiber. PMT6: Laser fiber should be on top of L bundle to PMT4, remove it from the velcro wrap.

NOTES: 1. Measure Tile Slot 1 at the bottom of the slot and Tile Slot 11 at the top

(where the widths are assumed to be minimum)

    1. Required shims make the minimum slot width in the range 4:4.5 mm
    2. Gaps are numbered starting at the ITC end.

NOTE: Tiles are numbered from the beginning of the cell, starting at the tile closest to the ITC end of the module. Count every other profile to count the tiles. Odd tile layers start at the cell boundary (count from the first profile), even tile layers start with a spacer plate (count from the second profile). The tile counting stick makes it easier to locate the tiles.
