=== 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
