DetChar Reports during ER1 |
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)
- Let's investigate the noise source which caused such a transition.
Check Spectral line noise
- Let's investigate the frequency, stability with more fine frequency resolution.
Open sitemap and access [sitemap] -> [DetChar] -> [Mnitors] -> [DARM lines]
- Let's investigate the frequency, stability with more fine frequency resolution.
Check Lockloss data
- Let's investigate the localsss causes.
Open sitemap and access [sitemap] -> [DetChar] -> [Lockloss]
- Let's investigate the localsss causes.
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
