Constructor & Destructor Documentation

CombinedMaterialEffectsUpdator::CombinedMaterialEffectsUpdator ( double  mass, double  ptMin = -1.  )

inline

Specify assumed mass of particle for material effects. If ptMin > 0, then the rms muliple scattering angle will be calculated taking into account the uncertainty in the reconstructed track momentum. (By default, it is neglected). However, a lower limit on the possible value of the track Pt will be applied at ptMin, to avoid the rms multiple scattering becoming too big.
