6064 no source (background), Using only Det B , 13 hrs, 31 min 11 sec long, 212 Hz, assuming a double pulse input : scaler = 91862/2=45931 seconds = 12 hrs 45 min 31 seconds, CODA data file has no "end_event" record indicating that I may have tried to write too many events and there was some data loss, the file is 2.0 G suggesting I reached the file size limit in CODA
