Overall Summary | DQ Shift Page

• 92.5% duty cycle for the 4 days.
• 50 Hz glitch line remains (since April 8th 2017).
• Starting on the 19th, we began to see clumps of glitches around 20 - 50 Hz (mostly ~30 Hz) . These glitches seem to be most frequent when ETMY optic pitch motion (most prominently 10 - 30 Hz) is at its highest. This can be seen on the SUS | OPLEV BLRMS page within the summary pages. I did not see any other noise correlations.
• Related to the above point, Hveto's most significant channel was consistently H1:SUS-ETMY_L3_OPLEV_PIT_OUT_DQ as it vetoed many of the 20 - 50 Hz glitches mentioned above. The corresonding YAW channel was number 2 in significance.
• We rode through a fair amount of EQs without too much issue.
