LHO ER7 data quality shift Wednesday 6/3 to Friday 6/5 (1117378816-1117584015). TJ Massinger was the shift mentor.

Things we noticed:

- Thursday the sensemon was incorrectly generating the inspiral range, which has since been fixed. The range was between 45 and 55 Mpc on Thursday.

- The calibration accuracy seemed to be more widely varying than in previous days, with large departures (factor of >5) at the high frequency (~6kHz) end.

- We saw the 14Hz roll mode ringing down at the beginning of each lock, except for the 11:00-13:00 UTC segment Thursday, where a ring-down measurement was being performed. Nothing to see here.

- Some ugly wandering lines in CARM around 600Hz that also showed up through their 4th harmonic.

- A particularly glitchy segment just before 18:00 UTC Friday. We tracked down the loudest glitch which was identified as 2.16kHz (SNR 3,190). A time plot shows this was actually high frequency glitches riding on a much larger ~7.7 Hz blip. The high frequency components also showed up in the PRM M2 suspension control signals.
