class HRichAnalysisSim: public HRichAnalysis
$Id: $ *-- Author : Laura Fabbietti <Laura.Fabbietti@ph.tum.de> *-- Revised : Martin Jurkovic <martin.jurkovic@ph.tum.de> 2010 _HADES_CLASS_DESCRIPTION HRichAnalysisSim This class besides the Rich Analysis contains the necessary functions to retrieve the parent track number corresponding to each pad that belongs to a Ring structure. The Ring Finding algorithm is executed by the class HRichRingFindSim. This class contains 2 different algorithms to find a ring, once a ring is found the track numbers of the particles that have hit the pads belonging to the ring structure are memorized in an array. (Int_t *iRingTrack). Once all track numbers are collected, 3 tracks number are saved ( HRichHitSim:track1....) for each Hit with the corresponding weights (cfr. updateHits). (The weight is the number of pads a photon or a Ip has fired.) A flag for each of the three track numbers is saved too, to be able to distinguish between a Chrenkov photon and a direct hit. use kSkip in the constructor to skip writing of event if no ring was found

HRichAnalysisSim(void)
HRichAnalysisSim(const Text_t* name, const Text_t* title, Bool_t kSkip = kFALSE)
~HRichAnalysisSim(void)
getPadsNTrack1(Int_t padx, Int_t pady, Int_t sec)
This function returns for each pad the corresponding NTrack1 value (cfr. HRichCalSim, HRichDigitizer::execute). All track numbers are stored during digitization in the catRichTrack Linear Category. NTrack1 is the index in the Track array corresponding to the first track for each pad. This function is called from HRichRingFindSim::CalcRingParamters.
getPadsNTrack2()
This functions returns NTrack2, which is the index in the Track Array corresponding to the last track for each pad. Pad must be identified by calling getPadsNTrack1(...) first.
getFlag(Int_t index)
It is called from HRichRingFindSim::LookForTrack(). This function returns the flag contained in the catRichTrack container at the position index. This flag is 0 for Chrenkov photons and 1 for IP.
getTrack(Int_t index)
This function returns the track number contained in the catRichTrack container at the position index.
execute()
updateHits(Int_t nSec)
Each Hit is stored, in addition to real data for simulated one the tracks number corresponding to each ring are stored too. Maximal 3 tracks are stored for each ring. The track numbers are sorted according to their weights.
sortTracks(HRichHitSim* )
Sorting tracks according to their weights Track with the highest weight is the first one
