Recent update
- 7/5 SNR threshold is lowered during 0am-8am. Instead, daytime events are all rejected.
- 7/5 Missing plot for PEM trigger channel is fixed.
- 7/4 ER events are reprocessed.

Overview
The main purpose is to study glitches and lock loss by visual inspection. Also, collecting information for glitch database is done through voting form for each glitch event. Using the result, we aim to do noise hunting, glitch characterization, and labeling for machine learning application. Here is slides describing how to use: slides
GlitchPlot uses trigger information provided by Omicron. GlitchPlot does clustering of the triggers and summarize the trigger information for each events based on the Omicron output.
For each events, plots for triggered channel and relevant channels are provided on Yuzu Summary. The relevant channels are basically chosen from
- Trigger channel
- Unsafe channels
- Important upstream channels
- Relevant VIS channels
- PEM near the trigger channel sensor
Following plots are provided:
- Time series
- Spectrum before trigger and after trigger
- Spectrogram
- Coherencegram with trigger channel
- Q-transform (Under testing)
The parameter for plots are determined based on trigger information.
Specification detail
For the exact channel list for each trigger, please refer $channelname.dat in GlitchPlot github.
