We tried adjusting the pitch of CPY to overlap the optical lever beam spot from the arm cavity side of CPY with the spot from the AR side of ITMY, but the PUM-level inter-chain earthquake stops limited our pitch adjustment. The figure shows that we reduced the distance between the spots we were trying to overlap by a factor of 0.56. If we are going to leave it this way, we should back off a little from this setting.
