virtual particleHit_t& cass::ACQIRIS::MomentumCalculator::operator() ( const Particle &  particle, particleHit_t &  particlehit  ) const

pure virtual

calculate the momenta

calculates the momenta of the particle form a given detectorhit. First correct the position of the detectorhit and the time of flight.

Returns

the particle hit that contains all momenta

Parameters

[in]	particlehit	the detectorhit to calculate the momenta from
[in]	particle	the particle object that contains the properties of the particle that the momentum needs to be calculated from

Implemented in cass::ACQIRIS::PzCalculatorMulitpleRegions, cass::ACQIRIS::PzCalculatorDirectOneRegion, cass::ACQIRIS::PxPyCalculatorWithBField, and cass::ACQIRIS::PxPyCalculatorWithoutBField.
