Work on installation of AMDs on ITMx and ITMy has been completed. 
Each test mass has now 4 AMDs glued to the suspension flats.  All AMDs on ITMy are glued slightly lower than the nominal AMD height position. It appears that quad suspension of ITMy is  ~5 mm longer than the ITMx quad. We have noticed it after AMD installation. This new AMD position should not cause any AMD performance degradation neither increase thermal noise according to our simulation.
Additionally, due to the scratches on the test masses flats we decided to move AMD 4 on ITMx and AMD 4 on ITMy. The exact gluing locations are shown in the attached drawing.
The curing dynamic test of the epoxy EPOTEK 302-3M of all batches was passed, see attached picture.  The bond between AMD and TM looks good for each AMD (see the back face image of the AMDs). 
We can call this installation 100% successful.
