Some supplimentary information:
- IMMT1 got three shilds (of the 4 surfaces), where as IMMT2 has only one sheild on the front.
- IMMT1 moved some reasonable amount as shown below, because of this big surgery. We did not move the positions back this time - leaving it for later with the main ifo alignment. The magnets or anything else were not touching anywhere. The oplev readings before and after this work were:
(Before)
IMMT1 PIT: -34
IMMT1 YAW: 48
IMMT2 PIT: 204
IMMT2 YAW: 19
(After)
IMMT1 PIT: 201
IMMT1 YAW: -251
(out of the range of the segments)
IMMT2 PIT: 216
IMMT2 YAW: 20
(did not move very much)
