Abstract:
This one-page document serves as a point of reference for all information / drawings needed to build the control systems for aLIGO Suspended optics.
Notes and Changes:
v9:
- Added OFIS and OPOS and associated mention of relevant DCC entries,
- removed reference to unmodified UIM,
- added other OSEM configurations for OPOS, OFIS, 4-OSEMs, added version numbers used for HAM-A drivers,
- added clarification of satamp used since many more SUS use US satamps these days,
- added Pitch / Yaw lever arms,
- added ITM / ETM ESD driver distinction.

v8: Updated DC Transconducance for modified TACQ drivers to better match measured data.

From v7: Updated M3 stage of HSTS to include possibility of modified TACQ driver. Also added the number of turns for an OSEM vs a BOSEM.
