GlitchPlot

This project is for glitch study. You can see the result on Yuzu Summary.

Feedback from users are very welcome ! Please inform C. Kozakai and H. Yuzurihara.

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.

Old information is more below.

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

Trigger clustering

For the trigger clustering method, please refer p3 of slides.

For the exact channel list for each trigger, please refer $channelname.dat in GlitchPlot github.

For the exact method for plot parametrization, please refer condor_jobfile_plotter.sh in GlitchPlot github. The intent and the variable name is as follows.
