Height measurement of ITMX

[Tomaru, Ushiba]

In this morning, we moved the security frame by several mm as the suspension is located at almost center of the frame.
Then, the height of the mirror was measured when the all keystone of the GAS filter are centered.

The result is -4 mm (the mirror center is 4 mm lower than the beam height, which is marked in 2017).
