HAM2/HAM3 work
Cheryl, Peter, Joe Gleason, Stefan

After making sure the input mode cleaner was flashing with a good alignment, we did the following alignment work for HAM2 and HAM3:
- IM1/IM2 tweak-up to center through the Faraday.
- IM3/IM4 tweak-up to center on irises marking the center of PRM and PR2
- Rotated the PSL polarization by 90deg (45deg on the lambda/2 stage) (required because of the REFL periscopes on HAM2)
- Installed irises for marking the IM transmitted beam, just after MC3 and before PRM
- Installed re-direction mirrors to redirect the IMC REFL into the path of IMC trans (alignment using the just installed irises)
- Joe is still aligning the last steering mirror in the IM4 transmitted path.

Update: I've positioned the final optic before the ISS PD and roughly aligned the beam to the ISS PD baffle. HAM 2 is now ready for the ISS PD installation.
