MICH ASC loop was implemented in ASC.py [*]. UGFs are maybe some tens mHz. See the error signal spectrum. As shown in the second attachement, the loops bring the AS_QPD{1,2}_DC darker. The AS camera looks darker with the loops. Gains are -0.05 and -0.001 for P and Y (not as shown in the screenshot).

In LSC_LOCK, at the FPMI_LOCKED state, ARM_ASC (ezca['GRD-XARM_REQUEST'] = 'ARM_ASC_ON' and so on) always broke the lock and also ITMY guardian is left FREEZE (why?), so they are now commented out just to avoid for now.

[*] there is some lame expressions in ASC.py line 160, 170. To be fixed.

By the way, we were taking that maybe REFL Q signals coule be better sensor for BS. It is also shown in the sensmat measurement.
