We succeeded in locking the OMC! (See the attached screenshot.)
We turned on the laser in the morning and went back to the control room in Mozumi to
work on the digital system. The transmission went low once but it went back in short,
which was probably not due to the mis-alignment as we did not see a higher mode.
Arai-san found some errors in the model and it was because we did not restart the
system after we changed the OMC model. Yamamoto-kun helped us and the error disappeared
once. Tuning some parameters, we succeeded in the end of the day.
