18  /*! @brief The TofQual cut.  /*! @brief A cut on energy release on S1.
  * This cut is done for each S1 layer: if there is one and only one hit paddle for the layer, then the dE/dX of the paddle (referred to a specified track) must be less than a fixed threshold. NOTE: 'hit paddle' means that both TDC signals are present AND they are both 'good' (according to TOF definition of 'good' TDC signal)  
19   *   *
20     * This cut discards events whose mean dE/dx on S11+S12 is greater than a specified functional form.
21     * Currently, this functional form is:
22     *
23     *    <dE/dx> < (3.102 - 2.6*TMath::Log(R))*(R<1.05) + 3.*(R=1.05)
24     *
25     * Since this cut uses the rigidity, it is necessary to enforce the existence of a physical track
26     * using #TrkPhsinCut before using this cut.
