Detailed Description

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

Definition at line 117 of file Kinematics.h.

Constructor & Destructor Documentation

◆ ~DoubleAngleComputer()

erhic::DoubleAngleComputer::~DoubleAngleComputer ( )
virtual

Definition at line 427 of file Kinematics.cxx.

◆ DoubleAngleComputer()

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.
