  /*! @brief Constructor.
  * The parameters are: the TOF-index for the track which is necessary to input to derive the beta and (resMax, qualCut and chi2Cut) for the quality of beta. Various combinations of quality parameters are possible: default low-quality beta (used for beta[12]): 10.,10.,20.; medium-quality beta: 5.,15.,4.; high-quality beta: 3.,20.,3.
  *
  * @param cutName The cut's name.
  * @param trackTof Pointer to the TOF-index indicating the track to be used when evaluating
  *        the beta (default value for TOF_index is 0, corresponding to the TOF stand-alone
  *        track [no TRK information to build the TOF stand-alone track]). The pointer to the
  *        TOF_index for TRK-track as given by TrkPhSinCut can be used.
  *
  * @param resMax Default: 10. (equivalent to beta[12])
  * @param qualCut Default: 10. (equivalent to beta[12])
  * @param chi2Cut Default: 20. (equivalent to beta[12])
