Detailed Description

Combines EnergyLossUpdator and MultipleScatteringUpdator. Adds effects from multiple scattering (via MultipleScatteringUpdator) and energy loss (via EnergyLossUpdator). Ported from ORCA.

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.
