Member Function Documentation

◆ recycle()

void KM3NETDAQ::JRandomTimeslice::recycle ( const double T_ns )

inline

Recycle time slice by randomly shuffling time intervals of data.

Hits within one time interval are swapped with hits within another -randomly selected- time interval.
Time intervals in which a high-rate veto occurred are excluded.

Note that the time interval should be:

(much) larger than time differences of hits in L1 coincidence; and
(much) smaller than time covered by data (as per KM3NETDAQ::getFrameTime()).

Parameters

T_ns	time interval
