Detailed Description

If needed, rotates the coordinate system of an Event so that the projectile 3-momentum lies along a desired direction.

Constructor & Destructor Documentation

marley::ProjectileDirectionRotator::ProjectileDirectionRotator ( const ThreeVector & dir = {0., 0., 1.} )

Parameters

dir	A 3-vector pointing in the desired direction of the projectile in the rotated coordinate system

void marley::ProjectileDirectionRotator::rotate_event ( marley::Event & ev )

protected

Helper function that does the coordinate system rotation.

Parameters

[in,out] ev Event whose Particle 3-vectors will be rotated

ThreeVector marley::ProjectileDirectionRotator::last_pdir_ = {{ 0., 0., 1. }}

protected

Stores the direction 3-vector for the last projectile that triggered a recalculation of the rotation matrix.
