NOTES:

5.3 The laser fiber bundles should go to the outside of PMT's 1&2 - except for the fibers going to PMT's 1,2,3 - fixed by RJM

The L bundle to PMT10 is on the wrong side of R bundle to PMT12 (fixed, RJM)

The Laser fibers to PMT 42,44 were interchanged, fixed, RJM

Laser fiber to PMT7 should be on the outside of E1 bundle - fixed, RJM

Laser fiber to PMT13 is wrapped around the rail - too much stress - fixed, RJM

5.4 A15-PMT30 - The left bundle is misrouted to PMT34

B14- PMT34 - Right bundle is misrouted ot PMT30

B11 - PMT10 - Left bundle is entangled with the R bundle to A13-PMT12 - should go under it as per model

Laser fibers should be routed outside of PMT1 - see model

None of the bundles have been marked before inserting into the aspirin tubes

All Problems fixed by MN

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