Yokozawa, Ushiba, Miyo
We moved PR2 mirror about -4mrad by using picomotor named IM_YAW beacuse PR2 was rotated several mrad in +yaw direction according to Yokozawa-san and Ushiba-san. Detail will be reported by them.
However we found that we need to move more in this direction by using traverser so that IM_OSEMs is in their sensor range.
So the alignment of the mirror was turned back with the pico motor again so that it would be the OSEM value before this work. (please see the attached figure)
