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)
5.	DetChar Reports during ER1	klog12282, klog12275, klog12264, klog12257, klog12205

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]

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
