=== Minutes ===

 * There is no paper about the coupling function method, but this method is already used in LIGO and Virgo.
  * Ask Virgo member about the acoustic noise paper, then contact to LIGO member
 * How about seismic motion paper?
  * 1 year data (seasonal data) with suspension
  * Ask Miyo-san about paper
 * PEM related paper (or internal document) in LIGO and Virgo 
  * https://arxiv.org/abs/1409.5160
  * https://pemcoupling.readthedocs.io/en/stable/how-it-works/how-coupling.html
  * GEO noise hunting 
   * https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=1693
 * Task management by GitHub
 * power line noise offline subtraction
  * Using ADC data in the OMC rack
  * by subtracting, amplitude became 1/10 (Other power line noise contribution?)
 * ADC assignment for offline subtraction
