## Function Documentation

 double LHAPDF::weightxxQ ( int id1, int id2, double x1, double x2, double Q, const PDF & basepdf, const PDF & newpdf, double aschk = `5e-2` )
inline

Get the PDF reweighting factor for two beams, one with id1,x1 and the other with id2,x2, from basepdf to newpdf

Note
For NLO calculations, in general different PDF values enter for each counterterm: be careful.
