== SimpleSctParSimAlg ==

The <code>SimpleSctParSimAlg</code> algorithm ([https://git.inp.nsk.su/sctau/aurora/-/tree/master/Simulation/SimpleSctParSim gitlab]) implements parametric simulation routine. Tools implementing [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/ICalorimeterTool.h <code>ICalorimeterTool</code>], [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/ITrackerTool.h <code>ITrackerTool</code>], and [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/SimplePIDTool.h <code>IPIDTool</code>] are required for actual simulation. A user can implement these tools with necessary logic. The following example tool implementations exist:

* [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/SimpleCalorimeterTool.h SimpleCalorimeterTool]
* [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/SimpleTrackerTool.h SimpleTrackerTool]
* [https://git.inp.nsk.su/sctau/aurora/-/blob/master/Simulation/SimpleSctParSim/SimpleSctParSim/SimplePIDTool.h SimplePIDTool]

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

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