Check of IR and GR overlap on First target/Second target/IR camera

Aritomi, YaoChin and Yuhang

To have a feeling of IR and GR overlap. We checked three points.

1. First target(shown in the attached figure 1 and 2). In the first figure, IR is actually in the center. When I was checking it, I could see the difference if Aritomi-san blocks or unblock the IR beam. In the second figure, there is GR. But it is difficult to tell the overlap level.

2. Second target(shown in the attached figure 3 and 4): It seems IR is higher and a bit left.

3. End camera(shown in the attached figure 5 and 6): It seems IR is also higher and a bit left.
