=== Agenda ===

 * LIGO PEM report 
  * LIGO Livingston O3 Commissioning Break (and other fun stuff) (Anamaria) [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11012|JGW-G1911012]]
 * Virgo ENV report
  * October 2019 Virgo commissioning break: report on activities (focus on Noise Hunting) (Federico) [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11010|JGW-G1911010]]
 * KAGRA PEM reports
  * KAGRA detector status & Update of the KAGRA PEM from last meeting (Yokozawa)[[attachment:PEM_191126.pdf|pdf]]
   * Change the accelerometers to beam direction
  * Status of Environmental noise hunting in KAGRA (Washimi)[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11013|JGW-G1911013]]
   * Slow Environmental Monitor should monitor not only day but also week/monty -> Already monitored
  * Brief summary of the DetChar activity Slides(Kozakai)[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=11011|JGW-G1911011]]
   * Can anyone use spectrogram tool? yes
   * Make frame file with selected channel -> Another issue
  * Seismic motion measurement(Francesca)[[attachment:KAGRA_francesca.pdf|pdf]]
  * Status of the PEM injection in KAGRA (TTanaka)[[attachment:meeting191126.pdf|pdf]]
   * Not distinguish coherence and incoherence for acoustic injection
   * Check different amplitude injection and check the linearity of the significance
   * Use aqccelerometer instead of the microphone
   * Reducing the uncertainty for the injection point. Wide injection->local injection
