Class DescriptionClass BrFfsTofMatchingModule Module scanning the global track table and picking up those matching valid tof hits. Selected tracks saved into a table of BrTofTrackMatch named "FFS Matching" Algorithm (Event method): ------------------------- 1- pick up tables of H1 hits and FFS tracks if one of them missing, return 2- Call method MatchTof(...) a- Select tof hits by checking the TDCs and ADCs of both tubes b- loop over tracks and sub-loop over hits i - evaluate the dX between track projection and hit position ii - minimize this distance and store the "winner" hit slat number in an array that has the dimension of the track table. It might be that the minimal dX is beyond the matching criterium, then, the hit id is -1 c- check "multiple hits" when more than 1 track share the same hit. In that case, ignore these tracks (it doesn't remove completely multiple hits since there might be one track only pointing to such hits - the other tracks having not been reconstructed) d- loop over remaining matchings and store result into table of BrTofTrackMatch object (cf class implementation file) 3- If FFS and BFS are aligned and if there are some matchings in H1 (a bit strict but ...), try the same game with H2 hits by swimming tracks through D3 and D4 and projecting on H2 ____________________________________________________________________ $Id: BrFfsTofMatchingModule.cxx,v 1.7 2002/04/16 11:48:17 ekman Exp $ $Author: ekman $ $Date: 2002/04/16 11:48:17 $ $Copyright: (C) 2001 BRAHMS Collaboration <brahmlib@rhic.bnl.gov> BrFfsTofMatchingModule() : BrModule() Default constructor.
