Following up on my alog 55023, I've replotted the data for the H1:ASC-AS_A_RF36_Q_PIT_OFFSET being set and zeroed during relocking. The new plot more clearly identifies the sequence of events, and now includes:
- Initial Alignment
- ISC_LOCK (state 110, where the offsets are set)
- the value of the pitch offset
- Lockloss during relocking (on the legend, labeled as "lockloss")
- H1 reaches NLN
- Lockloss from NLN (on the legend, labeled as "LL from NLN")
Attached:
- Example 1: H1 relocks without an Initial Alignment
- Example 2: H1 relocks after an Initial Alignment
- Relocking from 29Jan2020 to 5Feb2020
