NOTES:
10.2  D4 ODD, Layer 11, tile 15:  the fiber is short and bend radius into AT is too severe.  Fiber was replaced even though it did not give bad respnose on scan
         One fiber on cell B16, even side was cut by mistake when spare fibers were being removed.  It was replaced.
  These two repairs were not recanned at MSU.

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)
               2.  Required shims make the minimum slot width in the range 4:4.5 mm
               3.  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.
