DQ Shift summary:
- LHO was observing on average 48% of the time through out the week, with Wednesday only 1.9% (Issue with damping the violin mode at the beginning of the day, not sure what caused the detector not locking in the later half of the day)
- There was an obvious trend in the BNS range at the beginning of the lock: low BNS range (140-150 Mpc) going up to ~160 Mpc starting on Thursday; correlated with elevated broadband high-frequency noise; no clear correlation with glitch rate
- There were periods (1 - 2 hours) of elevated broadband 10-15 Hz noise throughout the week, especially with the short observing segments.
- Daily Hveto with usual suspects, except for Thursday: H1:PEM-CS_ACC_PSL_PERISCOPE_X_DQ (100 - 300Hz glitches)
- Line feature most obvious on Friday with ~ 1050, ~1160, ~1200, and ~1270 lines on the spectrogram. Fscan line count stays around 650 throughout the week.
- Sunday BNS range with extended periods staying around 150 Mpc, seems to have some correlation with some REFLAIR, VAC, PSL channels. Obvious broadband noise.
