'''Summary''':

(1) Miyo fixed the swapped cabling on the BF-damper for PRM with Nakagaki-san, and after that, the noise coupling of the transfer function at higher frequency is decreased to the same behavior of other PR suspensions (15994).

(2) Ikeda-san touched the picomotor of PRM for his first operation (15957) before measure the calibration factor between picomotor and OSEM.
