Detailed Description

Auxiliary data structure for list of hits with hit merging capability.

Definition at line 107 of file JHit_t.hh.

Member Function Documentation

void JAANET::JHits_t::merge ( const double  Tmax_ns )

inline

Merge hits on same PMT that are within given time window.

The earliest hit has the sum of the number of photo-electrons of all following hits within given time window.
The hit identifiers are subsequently set in ascending order, starting at one.

Parameters

Tmax_ns

maximal time difference [ns]
