Reference: TRANSMON ISC EX Layout D1201457

1. Put a reference flat mirror between M5 and telescope, and the beam didn't retroreflect when QPD servo was ON.
   1. This means that the bottom periscope mirror under the TMS ISC table is exonerated.
2. The beam was pretty well centered on M2 but too high on M1 and M3, so changed PIT if M2.
   1. We ended up splitting errors between M8 and M1, M1 being too high and M8 too low but good on M3.
3. Used M3 and M6 to steer the beam spot on the primary and the secondary to mimic what's supposed to be good according to https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=7285.
4. Used TMS BOSEM bias to rotate the entire thing so the beam retro-reflects off of ETMX.
   1. Unfortunately we needed a large YAW offset and the F2 and F3 DAC railed.
5. I'll talk with SUS people to find the best way to mechanically rotate the TMS suspension in YAW. We'll probably move the top blade.
