=== 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 of character of the range drop events significantly different?

      * 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

    * Are any of the most significant channels different from those of the previous days or shift. If yes, are there many other significant channels associated with the new channel(s). Are the associated channels ones

  * Fscan
    * Check for a new or disappeared lines, note down line information such as frequency, transition time

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]
