  23   KAGRAでのノイズを調べる
  24   KAGRA detector characterizationを共著者に加える?
  25   
  26   HasKALでレイリーモニターを実装した
  27   ノイズがガウス雑音になっていない、以上のことは言えない
  28   雑音がt分布のような裾を持った分布の場合はノイズを1つのパラメーターで表すことができる
  29   そのパラメーターをモニタリングすることで非ガウス性を評価する
  30   先行研究があり、一定の成果が出ている

  35   講演題目:KAGRA Detector Characterization:チャンネル間相関検出方法の確立
  36   講演者:譲原浩貴, 小野謙次,  神田展行, 端山和大, 山本尚弘, KAGRA collaboration
  37   講演者所属:阪市大理, 東大宇宙線

  39   講演要旨(200文字以内):
  40   大型低温重力波望遠鏡(KAGRA)は2015年末に常温での最初の運転を計画し、運転に向けての準備を進めている。
  41   KAGRAには主チャンネル以外に環境チャンネルが1万程度あり、それらの環境チャンネルを用いて効率的にノイズ源の特定を行っていく必要がある。
  42   今回はチャンネル間の相関を用いて、データに混入したノイズ源の特定方法について報告する。
  43 
  44   物理学会で2講演も話せるのか?(田越)
  45   -> 規約的にOK

  78   SNRの定義はLIGO?TAMA?(田越)
  79   LIGO定義に統一した方がよい
  80   日本国内でもLIGO定義に統一していく流れである
