Yokozawa-san adjusted the PR3 and SR3 mirrors. We could illuminate the ITMX, ITMY, ETMX, ETMY by Green lasers (not flash).
Except for ETMX, I think I can fit the taken image and update the mirror center. But, for ETMX, the power is not enough to illuminate the mirror. So, it's difficulut to obtain the presice mirror center by my script. (Dan-san's script might work.) If we obtain the GreenX flash or open the GV for EX, the image apperance might change.
