We passed all the steps foreseen even if through some small issues brilliantly tacked.
The system is left under position control on IP, F7 and Mar OpLev. The mirror is pre-aligned WRT the ITF reference.
Some work was needed to redistribute the load on the actuation cage according to the proper set point. This is needed as the mirror VS marionette
pitch alignment is now better than the previous thanks to the excellent work done by the payload crew on Thursday 0.1 mrad (!).
A special thank to the whole VAC crew, to the operator Menzione and Giuio Ballardin who helped to recover stepper motor operation.
We decided to postpone the installation of the safety structure !
The reason is simple: as we took it to unwrap and mount it, we realized that seat just by the safety structure two interesting object were looking upwards to Ettore. They are the two halves of the outer baffle lost and finally found !
After ten minute long brainstorming about the decision to be taken, we decided to install them later on.
The installation, to be performed without dismounting the payload, is possible as the first contact polymer is still there (in our plans it had to be peeled off tomorrow early morning before the evacuation. However, the installation requires some measures to be taken. They are clear but this is not the moment to unreasonably rush.
