Detailed Description

Function Documentation

directionalDeltaPhi()

double Rivet::ObjectBasedMET::directionalDeltaPhi ( const ThreeMomentum & first, const ThreeMomentum & second ) const

inlineprotected

Calculate deltaPhi with a possible minus sign. (i.e. so that phi(obj1) + deltaphi(obj1, obj2) always equals phi(obj2))

References Rivet::Vector3::phi(), and Rivet::PI.

update_matrix()

void Rivet::ObjectBasedMET::update_matrix ( Matrix< 2 > & mat, const double ptres, const double phires, const double pt2, const double angle ) const

inlineprotected

Update the 2D ((pT, phi)) resolution matrix given an object with pt and phi resolutions ptres, phires, pt^2 pt2, at an angle angle to the metvec.
