   * ETMYのダンピングとBSのL2P。ETMYは100urad程度だったのが、10uradくらいになった。あと一桁欲しい。
   * BSのLを押してPが出ないようにするフィルターを実装している。DCはうまくいったが高周波がまだ十分でない。
  * 先週の時点で干渉計ビームはX-armまでリカバーした。
   * 中央エリア内の温度変化によりPR2とPR3のGASが数mmのオーダーで上に上がってピッチが変わったが、角度でいうと10uradくらいのオーダーでずれるだけなのでOK, ただビームスポットはcmのオーダーでずれる。PR系を直すのは来週以降に延期。

  * 温度が一旦下がってから一度くらい上がった。問題なければ今のを保つ。		   * Alignment and Vibration Isolation: Izumi, Okutomi
   * BF yaw transfer function showed that it did not move well. It was fount that the position of IP was different from when pumping down started.
   * IP drifted 2mm in the air, and another 2mm when pump down. (Takahashi)
   * ETMY IPs were set back to where they were on 1/13. The transfer function now has the similar shape as before, but the Q of lowest peak is a bit low.

   * We can move moving masses of BF, or IPs of yaw to check TF can be recovered.
   * We will play one more day under vacuum.

  * Type A: *Yokozawa
   * RT model of Type A will be separated into cryopayload and tower.
