DQ Shift Summary:

• Duty factor of 80.39% for the week with range just under 120 Mpcfor most of the time
• Several hour stretchs of acoustic noise at the corner station near 21 Hz that doesn't show up in DARM
  • Does not appear correlated with periods of high wind
  • Listening to it makes me think of the fans on the vacuum racks or the HVAC system, but I'm not confident about either of those guesses
  • Can download a sample time where this appears here
    • This is time series data pulled directly from LigoDV-Web from Monday March 2 at 12:20 UTC
    • It is not whitened
    • Corners on the filter were 10 and 30 Hz
• Detector was in observing mode for a series of hardware injections leading to erroneous triggers
