AA diagonalized signal shows no difference when PR/BS local control is on/off (after using new BS PSD)

It was reported that PR/BS local brings noise to AA. However, after the replacement of BS PSD, the AA diagonalized signal shows no difference when PR/BS local control is on or off.

The comparison of the old case (blue curve: local control increase noise around tens of Hz) and the new case (red curve: local control doesn't increase noise) is shown in the attached figrue.
