=== Realtime model for DRMI commissioning ===
 * Requests from commissioning team
   * Calibrated signals of MICH, PRCL, and SRCL.
   * 10-20% error for each DOF
   * ASAP after DRMI will be locked.
 * Current status of RT model.
   * Filter processes of MICH, PRCL, and SRCL are constructed.
     * dL = C^-1^ * v,,e,, + (A,,TM,, + A,,IM,,) * v,,c,,

   * Channels are not registered to DAQ yet.
   * There are no CAL line to PRM and SRM.
     * Is there any plan of low-latency/offline reconstruction? -> Darkhan and Sawada-san.
   * Gain drifts by time are not taken into account.
 * What we need.
   * Optical gain (and cav. pole of PRC and SRC).
   * Actuator efficiencies of TM and IM of BS, PRM, and SRM.
     * Maybe the approximations as f^-2^  and f^-4^ are enough for 10-20% error.
