Continued, The TCam image analysis IX and EX
[STanaka, Toriyama, Yuzurihara, Yokozawa]

Today, we performed the TCam image analysis to find the edge of the sapphire mirror.
Different from Yesterday, we changed the suspension state from aligned to pay_float and injected the light closed from viewport.
Also, we performed the similar light injection to IX. But due to my mistake, I touched the receiver port with aligned state.
Thanks to Ushiba-san he recovered alignment with checking the photo-sensor value.
After this work, I performed the centering of TILT and LEN oplev.
TCam analysis will be appear soon.

After the centering ITMX TM OpLevs, I check the green transmitted light and alignment.
I used ADS to maximize the amount of transmitted light and modified the PIT and YAW of the ITMX by a few micro rad.
