Since we don't have any ASC for green lock, it would be useful to have the green ASC using ADS. The green ASC will run only during the lock acquisition and will be switched to the IR WFS after IR lock. I started the commissioning of the green ADS and checked the ADS error signal of FC2, which looks reasonable. 

I dithered the FC2 and checked the ADS error signal when FC2 PIT/YAW is moved (Fig 1). The dither frequency and amplitude is shown in Fig 2. The ADS error signal (PIT2/YAW2 DEMOD I) crosses 0 at the maximum of FC green transmission when FC2 PIT/YAW is moved. So we can use these signals for green ADS of FC2.
