Member Function Documentation

extrapolateXQ()

double LHAPDF::Extrapolator::extrapolateXQ ( int  id, double  x, double  q  ) const

inline

Extrapolate a single-point in (x,Q)

Parameters

id	PDG parton ID
x	Momentum fraction
q	Energy scale

Returns

The xf value at (x,q2)

extrapolateXQ2()

virtual double LHAPDF::Extrapolator::extrapolateXQ2 ( int  id, double  x, double  q2  ) const

pure virtual

Extrapolate a single-point in (x,Q2)

Parameters

id	PDG parton ID
x	Momentum fraction
q2	Squared energy scale

Returns

The xf value at (x,q2)

Implemented in LHAPDF::NearestPointExtrapolator, LHAPDF::ErrExtrapolator, and LHAPDF::ContinuationExtrapolator.
