Realignment after tidy up in July 2018

Participant: Eleonora and Yuhang

Beccause we changed many cables and arranged the control devices space, we think the green should be misaligned. Yesterday, I checked that it is totally misaligned!

I did the procedure of standard alignment of green: check target on PR chamber, check the first iris, check the second iris and match incidence with reflection, finally end mirror. After these procedures, I got the new offset of each mirror's local control offset. Then I can lock green and infrared together. See attached Fig.1

PR 0.3 -0.07
BS -0.11 -0.9
IM 0 1.1
EM 2.4 -2

I also found some problems and did some change during this process.

1. I connect the image of second iris to the third part of monitor. I also checked the light you can see in this second iris camera is corridor light. Because if I go to turn off the corridor light, it disappeared. See attached Fig.2

2. If you find problem in attached Fig.3, you need to reopen the program.

3. I tried to remote control of the second iris, but the network cable seems not working.
