Detailed Description

Computes DIS event kinematics from a mixture of hadronic and lepton variables using the double-angle method.

Constructor & Destructor Documentation

erhic::DoubleAngleComputer::DoubleAngleComputer ( const EventDis &  event )

explicit

Initialise with the event to compute. If the second argument is non-NULL, use the beam information from it in the computation. If it is NULL, determine the beam information automatically from the event. This allows the same class to be used with smeared calculations, where the beam information isn't associated with the smeared event itself.

Member Function Documentation

Double_t erhic::DoubleAngleComputer::ComputeQuarkAngle ( ) const

protectedvirtual

Scattering angle of struck quark.

Member Data Documentation

Bool_t erhic::DoubleAngleComputer::mHasChanged

mutableprotected

Stores whether the particle list has changed since the last computation of the quark angle.
