We confirmed the height of the breadboard (BB) in the OMC chamber. We measured the distance between the floor level of the OMC chamber and the top of BB with the laser leveler. The BB top was (135.5-80=55.5mm) higher than the 1000mm point from the floor. This height (1055.5mm) was consistent with the last confirmation (1058-3=1055mm).
