 * Yuki and Task managers: Schedule [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=8221|slide]]
 * Discussion of Pcal long time stability (Koki and Yuki)
 * Discussion of TF measurement for Y-end driver (Darkhan and Yuki)
 * Measurement result of density distribution of Gcal (Pang)
----------------------------
== Memo ==

 * Online:
  - IR X-arm lock comes back yesterday.
  - OLTF measurement (Low frequency)
  - unknown time delay (due to the high freq pole???)
  - DARM open loop(Current): measureing bw 10 - 30 Hz
  - Coil inductance -> Measurement?(Ask Takayuki)
   
 * Low Latency
  - Developing low latency with time dependency
  - Test will start from weekend (maybe).
  - How to estimate the smoothing effect?
  - We employ oplev infomations. Now, we are installing the sensors.
