Abstract:
Slides summarizing the current situation of in-vac steering mirrors.
- Around MCF and IFI (REFL related)
- Around IMMT1 (ISS related)
- Around PR2 and SR2 (ALS related)
- Around OFI and OMC (AS RF, OMC REFL, OMC TRANS related)

v4: Added AoI for IFI related steering mirrors based on JGW-E2112952
v5: Updated info for IMMT1 trans based on JGW-G2112943 and JGW-T2112949
v6: Corrected info for OFI and OMC steering mirrors based on input from Matteo Leonardi
