Notes and Changes:

The eLIGO Septum Window (D070069-A) has a minimum thickness of .75" to .88" on the drawing. Measured values for two of these optics are as follows:
LLO:
.8715" at thin edge
.9488" at thick edge
.738 deg
LHO:
.870" +/- .002"
The aLIGO wedged viewport window is specified on the drawing to have a minimum thickness of .870" +/- .008"
