SimpleSctParSimAlg

The SimpleSctParSimAlg algorithm (gitlab) implements parametric simulation routine. Tools implementing ICalorimeterTool, ITrackerTool, and IPIDTool are required for actual simulation. A user can implement these tools with necessary logic. The following example tool implementations exist:

SimpleCalorimeterTool

The SimpleCalorimeterTool tool implements the following logic:

  • Lower photon energy threshold (energyThreshold property)
  • Photon detection efficiency (deteff property)
  • Polar angle cut (maxCosth property)
  • 3D Gaussian resolution for energy, cos(theta) and phi variables (sampler property)

SimpleTrackerTool

The SimpleTrackerTool tool implements the following logic:

  • Minimal track transverse momentum (ptcut parameter)
  • Track reconstruction efficiency (deteff parameter)
  • Magnetic field (bfield parameter)
  • Polar angle cut (maxCosth property)
  • 3D Gaussian resolution for track vertex (vertexSampler property)
  • 3D Gaussian resolution for track momentum (momentumSampler property)

SimplePIDTool

The SimplePIDTool tool implements the following logic:

  • Probability of having PID decision (eff parameter)
  • mu/pi separation quality (sigmaMupi parameter)
  • K/pi separation quality (sigmaKpi parameter)
  • K/p separation quality (sigmaKp parameter)
  • electron id quality (sigmaE parameter)

       'ptcut': 50e-3,
       'bfield': 1.5,
       'maxCosth': np.cos(10./180. * np.pi),
       'momentumSampler' : {
           'mean' : np.zeros(3),
           'covar': np.diag(np.ones(3)) * 1.e-3**2
       },
       'vertexSampler' : {
           'mean' : np.zeros(3),
           'covar': np.diag(np.ones(3)) * 1.e-3**2
