- acoustic injection in the central building up to 10:00utc
- BPC noise injection from 16:00utc to 16:50utc
- alignment and suspension works
in the late evening the wind has suddenly raised up to 40/50 km/h (1st plot) that first unlock the itf then prevent the relock, so Paolo took the opportunity to do some test with this windy condition, work in progress...
-automation
to speed up the evening activity I remove the fmoderr tuning during the lock acquistion (fmoderr_skip = True in ITF_LOCK.ini)
-env noise
the 65 bump in the sensitivity and its lines in the environmental sensors are come back with us, they appeared during the acoustic injection and after a relock; the lines at ~71Hz and ~60Hz disappeared after a unlock/relock but the 65Hz line is still present (see 2nd plot).
Typo:
acoustic injection in the central building was up to 16:00 utc
