Full results from the DQ shift may be found here.

• During the shift, the combined duty cycle was 68.5%.
• The range was typically 70 +/- 5 Mpc except for 6 Dec when the range dropped below 60 Mpc after (about) 13:00.
• Excess noise appeared daily at about 13:00 - 14:00 UT in the. 50 - 100 Hz band. Glitches during this period found by hVeto seem to confirm that the cause is seismic. The timing of the excess noise is correlated with a bump in the 10 - 30 Hz BLRMS and appears to be caused by heavy vehicle traffic on Route 10 from 5:00 - 6:00 PST.
• All locks had features seen before: glitching in a band around 1083 Hz, strong bounce and roll mode ring-up at the start of each lock, and ring-up of the violin mode fundamental at the start of most locks.
• The 1083 Hz glitches remain a problem for burst searches. While hVeto often has rounds that find them, precise analysis of glitch times shows failure to line up with glitches in the apparently correlated channels. Thus, the cause remains a mystery.
