Shift tasks related with DetChar

Task No.

Theme

Substance

1.

Check SummaryPage works or not

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/monitoring/
Status should be OK

2.

Check Sensitivity & Binary range transition

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/
When you find some transitions, post to klog

3.

Check Spectral line noise (Yesterday)

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/yesterday/detchar/fscan/
When you find new or disappeared lines, post line information (frequency, transition time, etc.) to klog

4.

Check Lockloss data

See https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/today/
We can get the GPS time list at lockloss (GPS end)

Additional trial

  • Check Sensitivity & Binary range transition

    • Let's investigate the noise source which caused such a transition.

      Open sitemap and access [sitemap] -> [DetChar] -> [Bruco] (See JGW-G1809081)

  • Check Spectral line noise

    • Let's investigate the frequency, stability with more fine frequency resolution.

      Open sitemap and access [sitemap] -> [DetChar] -> [Mnitors] -> [DARM lines]

  • Check Lockloss data

    • Let's investigate the localsss causes.

      Open sitemap and access [sitemap] -> [DetChar] -> [Lockloss]

New suggestions for Detchar shift

You should change the interferometer state from ‘Locked’ to ‘Observing’ before checking the below details:

  • Summary
    • Has the average range changed significantly?
    • Is the number and character of the range drop events, significantly differ?
      • (To check how each range drop event behaves)
    • Are there any significant changes in the glitchgram?
      • Is any new or unexpected noise visible in the h(t) spectrogram?
      • Are there any anomalies in the glitch rate for loud glitches?
  • Lock/Sensitivity/glitches
    • Is there anything unusual in the hourly glitchgrams?
  • Lock/Sensitivity/strain
    • Is there anything unusual in the hourly h(t) spectrograms?
  • SEI/Ground/BLRMS_overview
    • Do any seismic gestures (earthquakes, anthrogrogenic etc..) appear to correlate with noise in h(t)?
    • PEM - all but especially seismic and acoustic
      • Are there any significant changes, especially new features, in the PEM channels?
    • Hveto
      • Hveto finds correlations between the h(t) glitches and glitches in other channels. Classes of glitches that might have the same cause are thus identified. “Significance” measures the strength of a correlation. Are any of the most significant channels different from those of the previous days or shifts?
    • Fscan
      • Check for a new or disappeared lines, note down line information such as frequency, transition time
