 * X arm: Cause of build up issue was tuned out that calm servo was broken. Transmitted light became stable with another circuit.
 * OMC: REFL port was consistent with that transmitted light had only 10%.
  * It means no significant loss inside cavity.
  * Still cause of 10% is not so sure. It could be mode matching.
 * CAL: MICH calibration is done. High frequency looks petty flat, ADC noise? Needs check whitening on.
 * PRM misaligned state did now work. It was tripped.
 * OMC: 700Hz oscillation comes from mechanical resonance of optical bread board. It was measured by accelerometer on the optical bread board.
  * It could be acoustic coupling, so pumping down may fix something.
 * OMC: Transmittance was 16% for input beam, 32% for TEM00, with sort of good alignment. Loss is 1% order inside.
  * Next week we may pull OMC.

 * COM: DC output of ASC PD had something wrong, and it was fixed on RT model.

 * VAC: GV were opened. Y arm can be tried tonight.
 * Type A was a lot better last night. Damping filter was modified at ETMY, <1urad.
 * Type B: SR3 has some big motion on yaw at 40mHz by ~6urad pp.

 * 5pm on Tuesday, PEM has a meeting with some interesting results.

 * DGS, AEL: SRM and SR3 18V was exchanged to the power supply from the computer room.

 * CAL: IMC whitening filter was engaged, but noise did not change.

Line 97: Line 109:
 * SRM needs some tuning, but probably OMC work has higher priority.  * MICH whitening fiter will be implemented soon for the engineering run this weekend.
