Minutes :
  * birefringence from TWE paper in circulation among co-authors
  * birefringence compensation paper in circulation among co-authors
  * report on thermal noise presentation during O5 task force :
    * no issue for thermal noise if loss are concentrated
  * new loss measurement from NAOJ coating (done by Waseda-san) :
    * does not show temperature dependence
    * similar level as KAGRA design
    * more measurements on-going
