Following aluminization, the tarp on the temporary cover will be replaced. The rotator is ready to install. Gear boxes have been aligned and the system is ready for installation. It will be installed after the next aluminizing attempt unless the weather precludes the aluminizing in which case the rotator will be installed. The actual testing will take place at SOML using the old illuminator.
Current progress is a reduction of the error by about a factor of two per week.
The profilometer can be used until the surface is better than about 100 nm.
