=== 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 [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=9081|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

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)
