- we reverted all the locking parameters to friday 18th at 12 UTC

the carm null 1f was not reachable (no loop oscillations), so we started to remove part to try to survive

- removed COMMp, CARM slow, alpha and Soft

the lock was killed by instabilities on the dark fringe, so Michal raised the shutter treshold to 0.027

we then tryed to lock with SR misaligned (-2urad ty) and we increased the jumps rate, see Figure 1.

The lock behavior is not predictable and no loop oscillations are present. It could be that we are too close to the cavity instability.
