Takahashi, Miyo (This report is about yesterday work.)
Before Akutsu-san and Yamamoto-san work for IMC recoverry, we aligned the MCO mirror which is not available yesterday and the MCE mirror.
We found the screw for yaw alignemnt of MCO was reaching to the limit of its movable range as shown in the attached file. This is the reason why we could not move the mirror in yaw direction by picomotor. After Takahashi-san rotated the screw a little by hand, we could rotate the screw by picomotor in remote. So, I aligned the MCO mirror so that the OpLev is centered. While I also aligned the MCE, I did not aligned the MCI because the its OpLev was out of range.
Please note that we should resolve the screw range before closing the chamber.
