_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
