I found many of the core optic (ETMs, ITMs, BS, PRM, SRM) suspension DOF damping controllers (SUSPOS, SUSPIT, SUSYAW, SUSSIDE) to be in various states of disarray:
- Many of the controllers did not have their "Cheby" and "BounceRoll" filters switched on.
- Some of the controllers didn't even have the Cheby or BounceRoll filters at all, or had other different filters in their place.
- ETMY was particularly screwy (I'll make a separate follow-up post about this)
- A bunch of random other unused filters lying around.
- oplev servos not on
I went around and tried to clean things up, by "normalizing" all of the DOF damping filter banks, ie. giving them all the same filters and clearing out unused filters, and then turning on all the appropriate filters in all core optic damping filter banks ("3:0.0", "Cheby", "BounceRoll"). I also went sure that all the outputs were properly on, and the oplev servos were on.
A couple of the optics had to have their gains adjusted to compensate for filter changes, but nothing too drastic.
Everything now looks good, and all optics are nicely damped.
I didn't touch the MC sus damping controllers, but they're in a similar state of disarray and could use a once-over as well.
