Subject: Arm loss 
Using the armLoss script (/cvs/cds/caltech/scripts/LSC/armLoss), I measured the round trip loss (RTL) of the arms.

The results are:
XARM: RTL= 171 (+/-2) ppm
YARM: RTL = 181 (+/-2) ppm

To get the results above, I assumed that the transmissivity of the ITMs are the same as the designed value (0.005).
This may not be true though.
