[Kitazawa, Furuhata, Kokeyama]
We connected AOM and AOM-driver.
AOM was already connected with short cable used for alignment (in September), so we had to change it to long cable for connection with AOM
driver.
We checked the signal from QPDs of IMC before and after the change, because it was feared that the beam is misaligned by the change.
The value of position (uncalibrated counts) indicated by QPDs were below.
[before]
IP1 : pich 0.24, yaw0.00
IP2 : pich 0.03, yaw0.18
[after]
IP1 : pich 0.25, yaw0.00
IP2 : pich 0.10, yaw0.18
IMC was locked successfully, although the value of IP2 was chaned a little.

And signal(X3,X5) of ISS servo was connected Universal Whitening filter(s1402921).
We have not set this gain yet, so We will set tomorrow.
As a result ISS model has to be partly change.
