          * Found correlation between wind power and BNS ranges
          * OMMT1 doesn't (maybe) have Oplev. It's better to confirm what kind of sensors were coneected.
          * BNS range channel has ~2min latency. It may become better results by considering the latency in BNS range calculation.
      * IMC commissioning
        * Noise investigation ([[https://klog.icrr.u-tokyo.ac.jp/osl/?r=16928|klog]])
        * Correlation between IMC and MIC sometimes increase in spite of no change in microphone spectra.
        * Coupling coefficients may be changed in time.
      * Cross check of hveto results.
        * Kihyun's (KISTI) and Chihiro's (Kamioka) results were confirmed as consistent each other.
        * For O4 observing run, Kashiwa environment is also important for increasing machine power.
        * Requirement of machine power should be estimated soon (but it's strongly depends on the situation of O4 joining)
        * We plan to use 100-200 aux. channels and it's very helpful to analyze them at the same time for each pipeline.
