Green am alignment

Hang, Jeff, Stefan

After all the grouting we had to do a rough manual arm alignment to see the transmitted beam.

After that we ran the baffle alignment script:

/opt/rtcds/userapps/release/asc/h1/scripts/ditherAlign.py

We also had to adjust H1:AOS-xxxx_BAFFLEPD_x_NOMINAL for thje script to catch the baffles (for some reason they were changed after O1).

That all went fine until the next double earthquake hit - Atka, Ak, Magtnitude 5.0 & 6.2. The attached alignment should at bleast let the green arms flash.
