The balance operation was not too easy, but the overall time spent was roughly similar to the usual one. Indeed, probably due to the damage on one of the ears occurred during fiber breaking in clean room. The problem was evident during the final assembly of the overall payload. Once the marionette was left lumped to its suspension wire, a large roll (and to some extent also pitch) appeared, then into the tower the effect was compensated using the counterweights on the marionette.
The motor cables position was optimized (pict)
However, in the end everything was managed and fixed.
- we should xcheck why the oplev was impinging too low on the reflector under the marionette. The verticla position of the suspension and its offset in the E direction will be finally reset and the oplev readjusted, also accounting for the misalignemnt MIR/MAR. This will be done later on.
- Vacuum operations can start.
