Following up Keita's Alog post 44420 we check other lock loss times on 10-4-2018 for POP A RF45 Q saturations.
- Out of 8 lock losses on 10-4, 6 show POP A RF45 Q saturating shortly before lock loss.
- It also saturates during lock sometimes
- According to the Alog the filtering of this channel has been changed to fix this problem.
- Summary page overflows page:https://ldas-jobs.ligo-wa.caltech.edu/~detchar/summary/day/20181004/detchar/overflows/
- Python code to make these plots: CIT: ~lundgren/aDQ/PreO3/FastLocklosses/H1locklosses_20181010.ipynb

we will update soon to add OMC DCPD sum to the plots.

See attached for full conclusions.
