Timing for the final measurements on 209Bi was determined for the new frequency 1.93777MHz. Peak positions are

PD NO 106
PD SO 141.5
PMT MIDDLE 45 (due to the broad temporal structure difficult to determine)

Center between PDs is 123.75. Difference to PMT MIDDLE is 78.75. This is ~3 bins larger than the half period of 75.
