class HParticleBt: public HReconstructor

_HADES_CLASS_DESCRIPTION


  HParticleBt

  This class contains functions to search rings in 1 event based on data
  provided by HBtMatrix.
 General strategy for RICH back tracking:
  - Use theta and phi angle information of particle candidate
    to point to ring center on RICH pad plane
  - Predict fired pads with the help of ring shape parametrization
    function
  - If at least one predicted pad is fired cluster information will
    be calculated
  - Fired pads are allocated to clusters of rings
  - Local maxima of clusters are searched and used to calculate the
    ring quality observable chi2
  - Number of all shared maxima per ring and shared maxima with a
    specific track are identified
  - User output is stored.
