  • Measurement of filter in the tunnel (Yamamoto)
  • Progress of Homework1 (Yuki)
  • Progress of Homework2 (Sawada)

  • Progress of Homework3 (Duotone-> Yuki, Swept sine -> Sawada)slide

Homework 1 :Error budget

• Check 1h or 2h data (60sec averaged data for kappas and fc).

Homework 2 :comparison b/w C10 and C00

• Apr.2 absent(Sawada)

• C10/C00-> Check the FIR and IIR model

• C10 power spectrum -> Web based monitor (1 week)

Homework 3 :Injection test related with timing and time delay

• Already prepared sine gauss template
  • Channel (ETMX, ETMY, DARM2, Pcal_Exc)

  • SNR(Pcal->4V, XY,X,Y-> template of swept sine)

• Analysis
  • We need to check.
  • April 1 or 2
    • Alignment, Weekly calibration

Homework 4 :Consistency check of h(t)/PCAL_X and h(t)/PCAL_Y
