Checked further inside the OMC chamber and made a punch list.

• As pointed out by Michimura-kun, all the steering mirrors in the OMC chamber should be replaced with newer ones. To do so, glueing the new mirror to the Thorlabs' Polaris C2G will be done next week.
• The rectangular pillar was detached and the standard pillar (circular) was in, alternatively.

We would need to continue the work in the next time, hopefully with stronger laser power (like locked in PRMI, bright...).
