GlitchPlot

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

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 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.

GlitchPlot uses trigger information provided by Omicron. GlitchPlot does clustering of the triggers and summarize the trigger information 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

Specification detail

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