Subject: IFO recovery - IMC alignment 

[Yuta, Paco]

We aligned IMC to recover the IFO progressively. First step was to center the MC REFL beamspot on the camera as well as the WFS DC. Then slide MC2 and MC3 together. Below are the alignment slider positions before/after.

  MC1 (before --> after) MC2 (before --> after) MC3 (before --> after)
PIT -0.3398 --> -0.4768 4.1217 --> 4.0737 -1.9808 --> -1.9308
YAW -0.8947 --> -0.7557 -1.2350 --> -1.3350 1.5598 --> 1.5638
