Before the implementation, we chosed each sensor which moved and got 0 when we moved the DC alignment. (Fig. 1), REFL WFS2 17I(fig.2). We implemented the integrator in the INP2_{P,Y} filterbanks so that each UGF become 50 mHz. Then, We turned off ADSs for IMMT2 PIT and YAW and closed the ASCs for IMMT2 PIT and YAW with REFL WFS2 17I. (Fig.3) When IMMT2 PIT error signal got 0, POP90 slightly decreased. But we succeeded in switching ADS to ASC with WFS for all of PRFPMI relative alignment DoFs.

We added the script which engages these ASC automatically in ASC_LOCK guardian.
