=== Discussion ===
 * Establishing the method of PD sensor matrix diagonalization has been tested at ITMY. It will be applied for cooling setup.
 * TF measurement on ITMY tower is going on. For whole damping control, PD sensor diagonalization is necessary.
 * Counting interference fringes due to Type A motion might be confirmed by Michelson or Y arm even during cooling down maybe.
 * We do not have so many days for Type A. Hopefully, we can start Y-arm commissioning after the big holidays.
