I've added a change into the H1_MANAGER Guardian that starts a one hour timer when we reach OMC_WHITENING to allow for violin modes to damp down if needed before moving to NLN. While waiting in OMC_WHITENING, the already existing two hour timer to reach NLN once the locking process starts is ignored as violin modes should be damping without the need for intervention. However, once the one hour timer expires, if ISC_LOCK has still not moved to NLN, H1_MANAGER will move to ASSISTANCE_REQ and initiate a call.

I've also removed some lines in the IFO_NOTIFY Guardian which I had added last year (alog72160) that allowed for an additional time after reaching NLN for ADS to converge and switch to camera servos before calling for help. Since the switch from ADS to cameras now happens before reaching NLN, this code is irrelevant.

All of these changes have been saved and loaded.
