The states are designed for in-lock adjustment of the spot position on PR2 and PR3. It is a guardian implementation of the scripts

So far, turning the PRC1 ASC loops off has to be done manualy.

Instructions

PR3_SPOT_MOVE:
WFS state: disable the PRC1 loop that ordinarily moves the PRM to center POP_A.
Use the PRM alignment sliders to move the beam spot on PR3. The scrips slaves all other optics in order to avoid taxing the WFS.

PR2_SPOT_MOVE:
WFS state: disable the PRC1 loop that ordinarily moves the PRM to center POP_A
Use the PR3 alignment sliders to move the beam spot on PR2. The scrips slaves all other optics in order to avoid taxing the WFS.
