OPS Mid-Shift Update:

• 00:52:37 UTC - went out of Observe for calibrations
• completed calibration measurements using JeffK's instructions
• addressed violin modes that rang up using Rahul's instructions
• found one violin mode gain in SDF, cleared
• found 12 CALCS channels in SDF, cleared
• 03:25:38 UTC - put H1 back in Observe
• 03:31:25 UTC - H1 kicked out for a violin mode gain
• stayed out to check all violin mode gains were not monitored
• found some on all 4 optics
• 03:44:38 UTC - put H1 back in Observe, while out of Observe, no H1 changes
  • SDF snapshots attached show everything I accepted or changed to Not Monitored
  • I un-monitored all TRAMP and GAIN channels for violin modes 1 through 20, all optics, (with 99% confidence that I didn't miss one)
  • two trend plots of violins, showing ring up with excitation, and ring down after damping applied
  • dtt plots of fundamental and second harmonic violin modes
    • green is at the max, before I applied damping to the modes that had rung up and/or had damping off
    • red is after the damping had been on for a while
