PMT timing relative to D30T001 is measured by splitting a pulse from a pulse generator .
PMT difference is determined by a coincidence measurement with the CF-252 source. The source was placed in the center of all detectors and 150.5 cm from the floor. The trigger detector is located 5.5 cm below the very bottom of the source.
