I added a PRM_SPOT_MOVE state similar to the PR2_SPOT_MOVE and PR3_SPOT_MOVE states (see alog <a href="https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=30754">30754</a>)
It allows moving IM3 to adjust only the PRM spot position.
To use it, just like with the other two scripts, turn off the PRC1 ASC loops.
The only issue with this state is that IM3 is very close to saturation already, so there is not much room.
